Working rail roads and their tracks.

I wonder what the guys in the cabs at each end of the car do? Notice they are not there when the train is moving faster.

It looks like there are hydraulic rams on each end of the depressed center part of the car and it seems to be made to ride extremely close to the rails presumably for maximum overhead clearance. My guess would be that they are there to control the rams to raise and lower the center of the car to clear switchgear etc., maybe in tight turns.

A few years back the UP 4014 Union Pacific Steam 4-8-8-4 was in Superior, Wisconsin. Can't believe I missed seeing it then.

The shop is still there, in fact that is where the 'Big Boy' shelters at.

Don't go around the crossing gates in Russia.

That setup here would eliminate most of the crossing incidents.

So, while watching a train last weekend, I wondered...

In a long train with 3 engines, how do they get all 3 precisely synchronized for equal wheel speed. Even just a few 10ths of a mile difference in speed between engines would logically seem to have potential for issues with traction, surging, drag, or something similar?

The locomotives are all computer controlled now. Whatever power setting the lead, or master locomotive is set at, the others are set at also. The systems monitor the traction motor current draws and rpm to keep all the axles pulling the same amount. In addition, there are wheel slip detectors that pretty much eliminate that problem.

The guy in the foreground is applying oil to the inside of the rail to cut down wear in the wheel flanges. In some areas, they used to have oilers on the rails that would apply lube to wheels on the outside rails of a turn to help them negotiate the turn with less friction.
