Penn Diesel on Horseshoe curve

[spikejones52002]

I was watching RFD.TV (again).

I seen a strange diesel. It was half again longer as the other diesels pulling around Horseshoe curve.

The entire under frame was a truck or 100% wheels. There was a "B" unit the same.

What was it and how did such a long truck track on the curve especially as tight as Horseshoe?

The quality or clairity was not good enough for me to catch the engine numbers.

Any information please.

If they were Centipedes, which sounds likely, you've run into one of the great mistakes in all of dieseldom.  They were built for PRR, SAL, NdeM plus two demonstrators from a cancelled UP order.  They were rated at 3000 HP each with a 2-D+D-2 wheel arrangement.  On PRR, they started out as mainline passenger power, but their unreliability soon had them demoted to pusher service in the Alleghenies.
