I've seen both but I spent 95% of my time on cars. Maybe someone else can comment?Are those brake shoes a composite material and or a cast iron material?
Why not put dynamic grids on the tender, fed by the drivers turning that big electric motor in the cab?Beautiful photos!
If that's all it has for brakes, I can see why it needs an accompanying Diesel with regenerative (?) braking to meet modern safety standards.
Can the steam pistons provide braking?
I worked at a sugar factory , used to move all the rail cars across the road to the pull line , always picked up broken coupler pins to use for drawbar used to find all kinds of goodies laying out in the yardI have RR experience when I worked for about 5 different car repair shops over the years as a welder. (ak carmen) This thread is about anything associated with RR's.
I'd guess you mean knuckle pins?I worked at a sugar factory , used to move all the rail cars across the road to the pull line , always picked up broken coupler pins to use for drawbar used to find all kinds of goodies laying out in the yard
So how do you swtich them out then? I was in the refurbishing business...Don't even need the knuckle pin if you keep the knuckle closed.....saw that many times
True but. UP keeps a diesel locomotive in the consist to power the cars. While 4014 has an onboard generator powered by steam, it's no where large enough for auxiliary car power.Why not put dynamic grids on the tender, fed by the drivers turning that big electric motor in the cab?
