Pennsylvania Railroad "T1" 4-4-4-4 Duplex Steam Locomotives - 1940's Trains in America
Pennsylvania Railroad (PRR) "T1" steam locomotives filmed in late 1940's. Includes scenes of the wheel slip that plagued these locomotives. "The Pennsylvania Railroad's 52 T1 class duplex-drive 4-4-4-4 steam locomotives, introduced in 1942 (2 prototypes) and 1946 (50 production), were their last-built steam locomotives and their most controversial. They were ambitious, technologically sophisticated, powerful, fast, and uniquely streamlined by Raymond Loewy." - information supplied by wikipedia - http://en.wikipedia.org/wiki/PRR_T1

[Politcalamity]

Thank you...for both posting rare and great footage of these giants in action...

...and for NOT putting some awful metal/country/new wave/dance song to it. Seriously, my hat's off to you for that.

The wheel slip problem on the T1 wasn't so much due to design but use. Many of the engineers who ran these locomotives on the PRR lacked sufficient training on them. There is a huge difference between a K4 and the T1. The PRR offered to sell some to the C&O, and sent two for the C&O to test. The C&O found them very fast and very powerful and in their reports do not mention wheel slip as a probleim.  They used to run large mallets, that experience could explain why they had no wheel slip.

Thanks for posting, this is a great video!!! (I think its a pretty rare video too)

its a shame they didnt save at least 1 for a museum

Fascinating video. Did the two sets of driving wheels have separate regulators or were they jointly controlled. I can imagine that wheel slip was difficult to reign in with a primitive control setup.

@harrodsburgNSfan - There's only one known sound clip of a T1 heading up Horseshoe Curve and it gives you a great idea of what the exhaust sounded like with the Poppet Valves combined with the Duplex Drive. Because they were two separate engines, the individual 'chuffs' fade in and out and when they're out of sync, the damn thing just roars like a jet engine. Look up 'T1 Horseshoe Curve'...you should find it.

Is it certain that neither Locomotives are still Assembled somewhere?

@JJosephS1 Keep in mind though. The T-1 only had 46% of total weight on the driving wheels as compared to 53% on the K-4s.

A fascinating video. These really are remarkable engines and it seems amazing they had such a short life. It's worth pointing out that most Pacifics with large drivers also slipped freely. Thanks for posting these gems.

Do I remember these these were first built by Altoona then later Baldwin, this was the same design used on the old Shark Nose. I remember when ATSF started to purchase these, but didn't due to a lot of mechanical problems.

Add sand to the lead truck and you would be laughing!
