Rail roads and their tracks.

The 4014 through Central Illinois this week. Love those brake pads.

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?

Are those brake shoes a composite material and or a cast iron material?

I've seen both but I spent 95% of my time on cars. Maybe someone else can comment?

Why not put dynamic grids on the tender, fed by the drivers turning that big electric motor in the cab?

I 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 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
