This photo is interesting, as it shows a 6-car train of old wooden “L” cars on the CTA’s temporary Garfield Park “L” trackage in Van Buren Street, possibly before service was transferred there in September 1953.

CSL 4081 and 7074 are heading northbound on Clark Street near Wacker Drive on June 13, 1947.

CSL 5814 is southbound on Wabash at Roosevelt Road on June 13, 1947. In the background, you can see how Roosevelt Road streetcars crossed over the Illinois Central tracks (and around Central Station) to reach the Field Museum and Soldier Field. This extension was built for the 1933-34 A Century of Progress world’s fair.

CSL 5960 is westbound on Grand Avenue at Wabash on August 21, 1947.

CSL 5395 is westbound on 63rd Street at the Illinois Central underpass, east of Dorchester, on June 13, 1947. The “L” has since been cut back to a point west of here at Cottage Grove. Its eventual destination will be Oak Park Avenue.

Philadelphia Transportation Company Birney car #1, signed for a fantrip sponsored by the Philadelphia chapter of the National Railway Historical Society.

Philadelphia Suburban Transportation Company (aka Red Arrow Lines) “Master Unit” car 83 is at the end of the line in West Chester, PA. Service on this interurban was replaced by bus in 1954, to facilitate the widening of West Chester Pike.

Red Arrow cars 82 and 80 are on the West Chester line, at a passing siding. This interurban was mostly single track, operating alongside West Chester Pike.

Red Arrow car 78, built by Brill in 1932, is at Newtown Siding in Newtown Square, PA on May 30, 1949 (on the West Chester route).

Red Arrow car 22, a double-ended 1949 product of St. Louis Car Company, is presumably at the west end of the Media interurban line. These cars, which closely resemble PCCs, are not classified as such as they used standard interurban undergear.

CTA gate cars and Met cars are on display at Laramie Yard in this August 1948 view (on the Garfield Park “L”).

North Shore Line 715 is on the Mundelein branch in July 1950.

On August 17, 1966, Pittsburgh Railways PCC 1542 is on Route 71 – Highland Park. (Richard S. Short Photo)

Chicago Rapid Transit Company 2731 is at Laramie Yard (on the Garfield Park “L”) in September 1936.

CRT 2881 is at Gunderson Avenue (in suburban Oak Park), one of the ground-level stations on the Garfield Park “L”, on September 19, 1934. This location is now the site of I-290, the Eisenhower Expressway.

CTA 3164 is at the Hamlin station on the Lake Street “L” in August 1948.

CA&E 421 is at Wheaton Yard in September 1936.

Don’s Rail Photos says CA&E express motor 5 “was built by Cincinnati Car in 1921 to replace 1st 5 which was built by American Car in 1909 and wrecked in 1920. It was retired in 1953.” Here, we see it in Wheaton in August 1948.

CTA PCC 4390 is presumably northbound at 95th Street, heading towards Broadway and Devon on Route 36 in August 1955. (Roy W. Bruce Photo)

Building Chicago’s Subways is dedicated to the late Charlie Petzold. His widow Beverly sent us this newspaper clipping, showing him with various family members in 1984, when the “L” was extended to O’Hare airport.

An early 1900s view of Chicago’s Union Stock Yards. The Stock Yards “L” branch can be seen at left. It closed in 1957.

CTA 6565 is eastbound on the Congress rapid transit line at Morgan on July 16, 1971.

A train of CTA 6000s waits for the signal to leave the terminal at Lawrence and Kimball on April 21, 1965. The Ravenswood “L” is now the Brown Line.

CTA prewar PCC 4023 is northbound on Route 4 – Cottage Grove circa 1952-55, having just crossed under the Illinois Central tracks.

CTA 4054 is on private right-of-way on the south end of the Cottage Grove line, running parallel to the Illinois Central Electric suburban service.

The date on this slide mount is March 1964. If so, this two-car train on the CTA Skokie Swift must be a test train, prior to the beginning of regular service in April.

CTA “Peter Witt” car 6287 is on the Cottage Grove private right-of-way on June 10, 1951.

North Shore Line freight motor 456 is running on battery power on a siding, as there are no overhead wires present.

On June 27, 1964, a two-car train of CTA 4000s is inbound running local service at Isabella. This station closed in the early 1970s and was quickly removed.

CTA red Pullman 238 is on Kedzie Avenue on a snowy January 17, 1951.

CTA PCC 4405 is southbound on Western Avenue on August 5, 1949.

CTA 6205, a one-man car, is on 87th Street in April 1951.

CTA 6203, another one-man car, is on the 93rd Street line in March 1951.

Since CTA 4406 is on a charter, this is most likely the fantrip that took place on October 21, 1956.
