Steam & Excursion > Brand New

Juniata built K4s 3761 in 1920, the same year John S. Powell framed it in the Philadelphia area with some rather nonstandard looking headend equipment. The first of the 50 K4s delivered in 1920 had piston rod extensions and a round number plates, but with an electric light, a distinction from previous versions.

The circular electric headlight made this better looking than the old rectangular headlight.

Maybe a horse-express car first out?

What terminal is EE ?
Marked on the pilot.

Anyone have a list of PRR engine terminal abbreviations ?

What was the purpose of the piston rod extensions?

This was discussed in previous posts dealing with the E Class.

Wanna provide a clue on which post?  Or am I not allowed to know?

 

Multiple posts over many days, not one isolated discussion. No definitive answers came from it all, if that's any consolation. The root reason for the coming and going of them remains speculative at best.

TO has a great feature called search. And it is free to use.

Such snarky answers from TO snobs.

The PRR had hoped the extensions would provide greater power from deeper compression inside the cylinder, among other guesses, but in the end, they did not work.  Trial and error was common back then with steam designs.

Just my opinion but, I don't think you know what the hell you are talking about! Also, those were NOT "snarky answers".

There was no condescending tone intended nor inherent in either of my replies, only the attempt to honestly answer the question as asked. Perception is an act of meaning, not an act of accuracy.
