1.) @mwichary The car was build in September 1975. The "BLT" is how you tell the age of the car. "LUB" is for lube or lubrication. "INSP" is for inspection.
2.) The colored bar-code-looking thing is just that, a bar code, just like on any item that you buy at the grocery store. It is the unique identifier for that particular piece of rolling stock, a way to track it as it moves throughout the continent.
3.) It has since been replaced by something that is far less eye-catching, a little laser-read device covered in a small piece of plastic. Modern railroads have "readers" along the track to record movements of rolling stock, and shippers can check on their shipments this way.
4.) Employees being on roofs of equipment could cause problems! It's an obvious safety hazard. The need to make the admonition likely is due to old habits being hard to break, as employees once needed to be on roofs to brake the equipment.
Whoa, that’s awesome, thank you. Why was braking on roofs once? Was it where the levers or controls were?
Yes, before Westinghouse invented the automatic brake about a century before, the cars had to be braked while the train was moving, and one brakeman was assigned to a certain part of the train and had to walk via the roofs from one car to another to loosen or tighten the brakes.
Jesus.
