CTA PCC 7213 is at the Clark-Arthur Loop in 1957, ready to head back south on Route 22 – Clark-Wentworth. The loop is still used by CTA buses, but the flowers have long since been replaced by asphalt. In the early morning hours of June 21, 1958, 7213 became the last Chicago streetcar to operate.

Robert D. Heinlein took this picture of CTA Met “L” car 2804 at the Laramie Avenue Yards on September 20, 1956. These wooden cars had been in use for 50 years on the various Met lines (Garfield Park, Douglas Park, Humboldt Park, and Logan Square), but were being phased out as more and more of the new 6000-series cars were delivered. The last wooden “L” car ran in regular service in November 1957 on the Kenwood line.

This picture was taken by Robert D. Heinlein on September 29, 1956, looking east from Asbury Avenue in Evanston. North Shore Line coach 738 is at the head of a westbound train. In the distance, you can see the former Ridge Avenue “L” station, which was used by Niles Center trains from 1925 to 1948. The station was later rented out to a business, but has long since been removed. CTA Yellow Line trains run here now. You can see why this was a favorite spot for photographers, but it was difficult to get a good shot here, due to the slow film speeds of the time (Kodachrome was ISO 10). Even with the lens wide open, shutter speeds were too slow to stop the motion of a train moving at speed. So the erstwhile shutterbug had no choice but to push the button while the train was still some distance away.

Chicago Aurora and Elgin wood car 307 at the Wheaton Yards in June 1961, after the abandonment. Don’s Rail Photos (via Archive.org): “307 was built by Niles Car & Mfg Co in 1906, It was modernized in July 1939.” It was not saved.

Pictures of South Side “L” cars on the center express track seem to be fairly rare, but here is one such train at 18th Street, looking north. The CTA stopped using the express track in 1949, when North-South service was revamped, with the closure of several stations, and A/B “skip stop” service was introduced. Not sure if this train is in service, or is just being stored here. I asked our resident south side expert M. E. about this photo, and here’s what he has to say: “This photo is a mystery.
You might think these L cars are being stored on the middle track. You might also think they are in service. Which is it?
Notice the white flags at both ends of the front porch. I think white flags indicate an extra section of a particular run. At least that was true about steam and diesel engines. But I would have to think the L used the same white flag system.
I would think there would be a destination placard hanging somewhere on the front of the first car. I see no such thing in the picture.
So which route would this train be on? Maybe, just maybe, it was a Shopper’s Special, which ran express between the Loop and Indiana Ave. If it is a Shopper’s Special, where is the destination placard? There would be no need for that placard if the train was running northbound. Then maybe the white flags indicate the end, rather than the beginning, of a train.
Or, because it has three cars, maybe it was an Englewood-bound train. I say this because a third car (either south- or northbound) would have been the Normal Park L car that was attached/detached from mainline Englewood service at 63rd and Harvard. (But, again, no destination placard!)
Whichever route it was on, this train was slapped together with different kinds of cars. The second and third cars are 4000-series from the 1920s, which had no porch. So this is a mixed consist. Mainline north/south trains were the Rapid Transit Company’s pride and joy. They would not have sullied those trains with mixed consists.
But if this train was simply being stored there, the question is why? Perhaps it was put there to be used later in the day starting in the Loop, then heading south. Maybe, once in use, it would display a destination placard.
If indeed the train was to be used later starting in the Loop, this middle track at 18th St. would likely have been the
storage track closest to the Loop. Yes, there were three tracks through the Roosevelt L station, but those tracks were used to store North Shore cars between runs.
There is a train in the background as well. I believe it is also sitting on the middle track, which would make it a North Shore train in storage.
Another question is, when was this photo taken? As you mentioned, after September 1949, with the advent of skip-stop service, no trains used the middle track. Also, looking at the trackage north of 18th St., I don’t see a ramp down into the State St. subway. The subway opened in 1943, and the ramp would have been constructed earlier than that, so this photo was probably taken no later than around 1940.
In conclusion: This train is a mystery.”

Under normal circumstances, Chicago Rapid Transit trains did not go down city streets like streetcars, but during World War II, they were sometimes used for troop movements on the Chicago North Shore and Milwaukee. Here is a four-car train of 4000-series cars on Greenleaf Avenue in Wilmette.

Long before the CTA Skokie Swift (today’s Yellow Line), there was the Niles Center “L” branch. It ran to Dempster Street in Skokie from 1925 to 1948, but as the area was just starting to be developed, there wasn’t much ridership.

“Saturday afternoon, January 30, 1954: Stub end of Normal Park “L’ (on 69th Street, east of Halsted), taken shortly after closing of branch.” Until the CTA Dan Ryan line opened in 1969, this was the farthest south the “L” went. Now the Red Line will be extended to 130th Street. (Robert A. Selle Photo)

We are looking west from the North Shore Line station in Libertyville in January 1963, the month of the abandonment.

A 1926 view of the Chicago Aurora and Elgin’s Wheaton Yard.

An early postcard view of the Aurora Elgin and Chicago (predecessor of the CA&E) yard in Wheaton. This may be from the World War I era as there only seem to be wood cars present.

Chicago Aurora and Elgin 453 in its original paint scheme, which was somewhat different than how it looked later on. In particular, lettering was done in Futura, a modern font, as the ten cars 451-460 were the most modern CA&E ever had. Delivered in late 1945, this was 18 years after their previous new car order. 453 is now at the Illinois Railway Museum, where it is being restored to this classic look. The car behind it is 451, which IRM also has.

Two views of Chicago Aurora and Elgin car 10, both likely from the same Central Electric Railfans’ Association fantrip, circa 1939 or so. Don’s Rail Photos (via Archive.org): “10 was built by Niles Car in 1902. It was rebuilt with a baggage compartment in 1910. It was later removed, but then reinstalled in April 1933 for funeral service. It was wrecked September 10, 1948, and scrapped.”

The late Charles L. Tauscher took this picture of CTA red Pullman 144 on one of those latter day Chicago streetcar fantrips. I am not sure of the location, but the film was processed in June 1958, which would imply this is South Shops at 77th and Vincennes (and the car on the right has a 1958 Illinois license plate). By that time, there was just one streetcar line left– Wentworth on the south side. 144 is now at the Illinois Railway Museum.

Don’s Rail Photos (via Archive.org): “Aurora Elgin and Fox River Electric 303 was built by St Louis Car in 1924, (order) #1306. In 1936 it was sold to CI/SHRT as 303 and in 1954 it was sold to CP&SW (Columbia Park and Southwestern, aka Trolleyville USA) as 303. It was sold to Northern Ohio Railway Museum in 2009.” Here, we see it in Cleveland (Shaker Heights Rapid Transit) on October 23, 1954.

This is certainly a view of the Stock Yards “L” that I have not seen before. Robert D. Heinlein took this picture on September 28, 1957, not long before the branch was abandoned. Note the unique single-track operation here, unlike anything else on the system. CTA wood car #2906 is at the Armour station, which the photographer noted was located at Racine Avenue (1200 W.) and 43rd Street. The Union Stock Yards was already in an irreversible decline by this point, and would close for good in 1971. The “L” ran in a loop through the yards and back to the main line station at 40th and Indiana Avenue. It always operated as a shuttle, except possibly when there was a major event at the International Amphitheater. Our resident south side expert M. E. writes, “Your last sentence says “It always operated as a shuttle, except possibly when there was a major event at the International Amphitheater.” I respectfully disagree about the “major event” part. At 40th and Indiana, the Stock Yards L approached Indiana Ave. from the west. Mainline trains from downtown also approached Indiana Ave. from the west. The Stock Yards and mainline tracks ran parallel. Switches that connected the Stock Yards line and the mainline were also west of the Indiana Ave. station. Any mainline train from downtown, if it were to offer direct service to the International Amphitheater, would have to change direction, negotiate the switches, and head west on the Stock Yards line. I think this would have been a clumsy if not dangerous practice — perhaps requiring a motorman at each end of the mainline train — and it would have delayed L traffic on both the mainline and Stock Yards line. Ergo, I can’t imagine a direct connection from downtown to the Stock Yards line. But if a mainline train came into Indiana from the south, such a “transfer” would have been possible. A mainline train would first stop at Indiana, then proceed to the switches and move to the Stock Yards line, probably with minimal disruption to both lines. Still, it would not have been worth doing, because of much less L patronage from the south versus from downtown. A Stock Yards shuttle train usually had only one car, but for special events at the International Amphitheater, the Rapid Transit Company ran two-car trains, sometimes using the newer 4000-series cars for more capacity.”

CTA PCC 4391 is northbound on Wentworth Avenue at 40th Street in June 1958, the last month of service. That’s the old Stockyards “L”, which had been abandoned the previous year and would soon be removed. Everything to the right here has now been replaced by the Dan Ryan expressway. Car 4391 was the only postwar PCC saved, and is now at the Illinois Railway Museum. (Charles L. Tauscher Photo)

A group of sailors boards a northbound North Shore Line train at Adams and Wabash on the Loop “L” on September 4, 1961.

And here’s the view looking the other way, as North Shore Line Silverliner 761 enters the Milwaukee Terminal at 6th and Clybourn. This negative was undated, but from the automobiles, I would say this is circa 1957.

“Electroliner at Milwaukee, Wisconsin, entering station from street with policeman directing traffic, June 18, 1962.”

I realize this is not the greatest picture, but it does show the CTA Forest Park Terminal as it looked on June 27, 1958. We are looking north, as the Abell-Howe company was located at 7747 W. Van Buren Street. The yard was being rebuilt at the time, in conjunction with construction of the Congress expressway nearby (now the Eisenhower). This work carried over into the following year. Six days before this picture was taken, the new Congress rapid transit line had opened as far west as Cicero Avenue in the highway median. West of there, there were temporary tracks. The new alignment went into use in 1960. This slide was shot on Anscochrome film, which was cheaper and inferior to Kodachrome. In the close-up, you can see how grainy it is, making it look similar to an Impressionist painting. The difference is that Kodachrome was basically black-and-white film, where the colors were added in the development process, while Anscochrome, Ektachrome, and Fujichrome have the colors built into the film.

North Shore Line 761 is at the head of a three-car train of Silverliners in North Chicago. (G. Millen Photo) This was scanned from one of those early Ektachrome slides that has faded to red. This time, we were able to restore the colors pretty well.

I recently received this real photo postcard and did some restoration work on it. I would say it dates to around 1907, as there are areas on both the front and back where people can write messages. 1907 was the first year when the post office allowed messages on the backs. There is a document visible in the picture from the Metropolitan West Side Elevated in Chicago. Given the presence of railroad lanterns, this is likely a behind the scenes view of one of the early “L” companies, which began service in 1895.

Here is a classic red border Kodachrome view of a Chicago and North Western steam-powered “scoot” circa 1955, just leaving North Western station in downtown Chicago. E class 658 was built in 1922. The 4-6-2’s original number was 1658. Bill Shapotkin adds, “The photo was taken in Chicago at Clinton St Tower — where the West Line (Galena Division) splits from the North (Milwaukee Division) and Northwest (Wisconsin Division) Lines. The train at right is an outbound Northwest Line Train. The train at left MAY be backing into Northwestern Station (hard to tell). View looks E-S/E. Photo taken pre-Oct 1956 (when steam last operated on the C&NW).”

Here is a classic April 1968 view of PTSC Red Arrow Lines Rail Bus #409. The Rail Bus was an attempt by Merritt H. Taylor Jr., head of the privately owned Philadelphia Suburban Transportation Company (aka Red Arrow Lines) to create a vehicle that could operate via railroad tracks and ordinary streets. There were two such buses adapted in the 1967-68 experiment. 409 was standard gauge and 410 was Pennsylvania wide gauge. 409 operated on the Norristown High-Speed Line. Ultimately, the experiment was not successful, and Red Arrow was sold to a public agency (SEPTA) in 1970. (F. I. Goldsmith, Jr. Photo)

NYCTA Rapid Transit Lo-V #5466
Location: New York City (Near Stillwell Avenue, Coney Island Terminal)
Date: November 14, 1965
Photographer: Unknown
Here is a classic view of a New York City Lo-V subway train, operated by the New York City Transit Authority. The landmark Brooklyn Union gas holder is also visible in the picture. The occasion seems to be a farewell fantrip for the Lo-Vs. These cars were built by American Car & Foundry in 1924 for the IRT (Interborough Rapid Transit Company).
From the Wikipedia:
“Low-V” is short for “Low Voltage”, which refers to the cars’ form of propulsion control. Earlier Composite and “High-V” (High Voltage) equipment that ran on the IRT had utilized a 600 volt DC circuit that ran directly through the motorman’s master controller to control the car’s propulsion. The 600 volts was also trainlined through the whole train by the use of high voltage jumper cables, which had to be run between cars. However, the Low-V equipment used battery voltage (32 volts) in the motor control circuit to move high voltage (600 volts) contacts underneath the car, which would control the car’s propulsion. Likewise, it would no longer be necessary to use 600 volt jumpers between cars. This tremendously improved the safety of the equipment for both train crews and shop personnel alike.
Today’s operator, the Metropolitan Transit Authority, has retained a set of Lo-Vs, which are used for special occasions, such as opening day at Yankee Stadium. Car 5466 is now at the Branford Electric Railway Association in Connecticut.

New Orleans streetcars have a long history, going back to 1835, when horsecars were first put into service. The St. Charles line has operated continuously since then, except for a period after Hurricane Katrina. The streetcars pictured here (972 and 836) were built in the 1920s by the Perley A. Thomas company. This picture was taken on June 7, 1960 by noted railfan photographer Clark Frazier.

Date: August 1971 (processing date)
In the early 1900s, the Milwaukee Road electrified over 600 miles of freight trackage in the northwestern United States. Use of electric locos ended in 1974. This was a very picturesque, if not a profitable, operation. Large parts of it were eventually abandoned. M. E. adds, “Your caption mentions freight trackage. Passenger trains used this line too, particularly the flagship Olympian Hiawatha. The electric locomotives in the picture were called Little Joes (after Joseph Stalin) because they were originally intended to go to Russia, but the U.S. government negated the shipment. The Chicago, South Shore and South Bend also had some Little Joes. By the way, the Milwaukee Road used electric locos to go through tunnels safely. There was a second section of electrified trackage in Washington State as well.”

CTA “L” car 1 was built in 1892 for the South Side Rapid Transit Company. Since this photo was taken, it was moved to the Chicago History Museum, where it is on display. CTA cars 4271 and 4272 were built in 1923 by the Cincinnati Car Company, and were the “state of the art” rapid transit cars of their time. They are part of the CTA Historical Fleet. M. E. adds, “Maybe THIS is the configuration of cars in the “mystery” photo at https://i0.wp.com/thetrolleydodger.com/wp-content/uploads/2023/10/aaf472a.jpg . And I appreciate Andris Kristopans’ thought that this train was awaiting a deadhead trip to Old Congress to start a southbound mainline trip in the afternoon rush. But that would mean, on the way south, the porch car led the train. That baffles me if the train was an Englewood train, because the detachable Normal Park-destined car (an older porch car in the 1930s and 1940s) was always at the rear. Either I am wrong, or the Rapid Transit Company occasionally put a porch car in the front — on an Englewood or Jackson Park train — and I never knew that. Here’s another thought: Maybe this picture was taken while the Rapid Transit Company was still getting new 4000-series cars, and at that time there were not enough 4000-series cars to form complete trains, so the porch car was still necessary. But the 4000-series cars arrived in the early 1920s. Could this photo be that old?”

From the Wikipedia:

The Delaware River Bridge, now the Benjamin Franklin Bridge, was designed to accommodate both rail and road traffic. When it opened on July 1, 1926, it had two outboard structures beside the main roadway for rail and space for two streetcar tracks (never installed) on the main road deck. Construction of the rail line did not begin until 1932, and the Bridge Line opened on June 7, 1936. Relatively short, it only had four stations: 8th Street and Franklin Square in Philadelphia, and City Hall and Broadway in Camden. Connection was available to the Pennsylvania-Reading Seashore Lines at Broadway.
In Philadelphia, the line joined the 1932-opened Broad-Ridge Spur just west of Franklin Square and shared its 8th Street/Market Street station. An underground tunnel continuing south following 8th Street then west following Locust Street to 18th Street, had been started in 1917 as part of plans for a Center City subway loop. The shell of this 8th–Locust Street subway was completed, but not outfitted for passenger service, in 1933. Beginning in June 1949, Bridge Line and Ridge Spur services were through-routed, providing one-seat service between Girard station and Camden. Construction on the 8th–Locust Street subway resumed in 1950. Bridge Line service was extended to 15–16th & Locust station, with intermediate stations at 12–13th & Locust station and 9–10th & Locust station, on February 14, 1953. This section is owned by the City of Philadelphia and leased by PATCO.
Extension to Lindenwold
Despite the extension, Bridge Line ridership was limited by high fares and not extending east of Camden. In January 1954, due to low ridership on the extension, off-peak service and Saturday again began operating between Girard and Camden, with a shuttle train operating between 8th and 16th stations. Sunday service was suspended west of 8th Street at that time due to minimal usage. By 1962, only 1,900 daily passengers boarded the line west of 8th Street.
To facilitate the construction of extensions in Southern New Jersey, the states expanded the powers of the Delaware River Joint Commission (which owned the Benjamin Franklin Bridge and the New Jersey portion of the Bridge Line), rechristening it as the Delaware River Port Authority (DRPA) in 1951. The agency commissioned Parsons, Brinckerhoff, Hall & MacDonald to study possible rapid transit services for South Jersey; Parsons, Brinckerhoff’s final report recommended building a new tunnel under the Delaware and three lines in New Jersey. Route A would run to Moorestown, Route B to Kirkwood (now Lindenwold), and Route C to Woodbury Heights. A later study by Louis T. Klauder & Associates recommended using the Bridge Line instead to reach Philadelphia and suggested building Route B first, as it had the highest potential ridership.
Over the weekend of August 23 to 27, 1968, the Ridge Spur was connected to a new upper-level terminal platform at 8th Street station to allow conversion of the Bridge Line into the “High-Speed Line”. Bridge Line service was split into 16th Street–8th Street and 8th Street–Camden segments during the conversion, with a cross-platform transfer at 8th Street. Bridge Line service was suspended on December 29, 1968, for final conversion of the line. Service from Lindenwold station to Camden along former Pennsylvania-Reading Seashore Lines trackage began on January 4, 1969; full service into Center City Philadelphia over the bridge began on February 15, 1969. The Lindenwold extension cost $92 million.
