Eh, it may be me - or other built in loco's not behaving realistically.
They seemed to loose some power (although when I mentioned this before, other's expressed that it was more accurate (?))
And they seem to loose steam volume very quickly. By which I mean if I drive them right away, no problem really, but if it sits for awhile while I'm switching cars with another loco or something, when I get to Ben's loco I see full boiler pressure AT FIRST, but once I've moved a few feet the pressure drops to almost nothing.
I'm told that it's because I need to open the blower, but that doesn't seem to build any pressure back up...
