Thanks Mayner.......I figured the tank would be part of the braking system but didn't know if a compressor would have been needed for a relatively short run, (by US standards). In other words, was the tank filled at the start of a run and it would last the entire run? I'm familiar with vacuum systems as they were used by the various Maine 2' railways but the engines always seemed to be fitted with an engine mounted compressor.
If the tanks were fitted later in life......then perhaps that tall, thin column at the driver's door was part of the braking system??
I also noted the piping running along the footboard forward to the brake hose at the front end (and I assume the cab end)
I will be using RC/battery. Haven't decided on what system to use just yet.......have to make a decision on "sound" first.
Now I will want to build up some rolling stock to run with it!
thanks again......tom
