I have been into trains just about all my life.
I was shocked when they showed a pan system that allowed for a moving and even high speed water pickup into a steam locomotive tender. up to 80 mph they said
Basically a big long pan between the tracks two foot wide and up to 2,500 ft long and then a shute/scoop under the loco would suck/shoot water up into the tender.
I NEVER HEARD OF SUCH A THING BEFORE.
and surprised that I have not seen anyone model it either.
They say this was used so that passenger trains could make better time and not have to stop and use a standard water tower "pipe thingy" (sorry can't think of the word right now - it's late 11:55pm)
