E7 fuel tank detail


The E7 replaced the E6 on EMD production lines in 1945, and was the first E-unit to replace the "slanted" nose with the "Bulldog" style seen on F-units. E7s were in use into the 1970s, but all the survivors were scrapped save PRR 5901, which is now at the Railroad Museum of PA. It was donated in Penn Central colors, but has since been restored to the PRR scheme.

PRR Streamlined Steam switcher patent

This one is new to me - a 1945 PRR patent (issued 1952) at first glance I thought "diesel switcher" but its a *steam* design!

GG-1 4800 "Old Rivets" walk around

The original (and only riveted) GG-1 prototype, as seen preserved at the Railroad Museum of PA. Note the original type screens - these were moved higher up after "diamond" snow shorted out motors during several blizzards in the 50s and 60s - 4800 lasted in service almost to the end of the GG-1 era, but she apparently never received the retrofit.

4800 was delivered to the PRR in the summer of 1934, having been built by GE/Baldwin to compete with Westinghouse's R1. The Pennsy was looking to replace the P5s, and the GG-1 was chosen due to its articulated frame, which allowed the design to take sharper curves than the R1.

Seen here unmarked in overall black, 4800 saw service in a bicentennial scheme before becoming the sole GG-1 to wear Conrail blue before being retired to Strasburg.





GG-1 4800 Builder's Plate





The GG-1 had six driving axles, with 57-inch wheels, with a quartet of unpowered wheels at either end. Each powered axle had a pair of 385hp traction motors; the locomotive was rated for a continous output of 4,620hp, and for a short duration, 8,000hp could be achieved. In passenger service, GG-1s had a timetable speed of 75-80mph for the majority of their lives, but in later years this was increased to 100mph on several occasions.

PRR D16sb 4-4-0 Steam Locomotive

Hardly the best shot, but still kind of interesting - this example of the classic 4-4-0 "American" was built at Juanita, PA for the PRR, and later ran with the Strasburg Railroad until at least 1989. Presently, she's across the road at the Railroad Museum of PA.


The once nearly standard 4-4-0 was considered obsolete by the late 1800s, but the PRR was to build over 400 D16s between 1895 and 1910. Larger versions of the earlier D14s, these were engaged in secondary service, in decreasing numbers, until the early 1940s. The D16sb designation refers to locomotives rebuilt with superheat.
