If you guys will go back in railroad history and read about "Pony
Engines" you will find this same senerio. In the switching yard, pony
engines did not have steam boilers.
They were hooked up to prime locomotives to load a large holding tank
with super heated water. The pony engine would move rail cars around
the yard and do all the
necesary switching etc. by injection and flashing the super heated water
into motive steam very simply. You are revamping history. Norm
