Re: Railroad Thread

I wonder if under the right circumstances, train brakes being more effective could make the rail move fore-and-aft?
It’s firmly connected to miles of rail each direction so it can’t slide too much.

Brake summary

Anyway, dynamic braking or not, non-locomotive cars are surely still fitted with brakes, right? RIGHT? The general discussion is braking & effectiveness. Trains have four “systems” -Air-powered friction brakes on cars. -INDEPENDENT air-powered friction brakes on the locomotives -Dynamic brakes ...

Re: Railroad Thread

There was a classic runaway train Swiss cheese automation fueled derailment in CA. First, the dispatcher didn’t know what he was doing, fudged on car weights and maybe even sent the train without enough locomotives. The train had front and rear locomotives- not_electronically linked, but crews and r...

Dynamic brakes:

From YouTubez and rail perving, it’s been my observation that dynamic brakes aren’t half bad at slowing a train. Conversely it’s one unit working to stop 30 to 40 cars or more so it can’t be THAT effective…you got 6 axles of braking vs 160 axles of momentum. 16:1, roughly.

As Flyboy once told Evan, if you want to affect something, go into the industry. Proclamations on internet fora (especially train advice on an obscure aeroplanie forum) don’t do much.

Re: Railroad Thread

In any case, having a gazillion ton vehicle with a gazillion wheels and a gazillion brakes and have it slow down at 0.5 MPH per second at best is either stupid, or bad engineering, or there is something wrong with the condition of the brakes and people don't care. It is so ridiculous that it defeat...

Re: Railroad Thread

I think the wheels generally turn during emergency braking, making the brake-pad-wheel the weaker link, BUT wheel lock/rail slippage is not_unheard of. One other trivia (again, ass-hat outsider blathering). Because of the time it takes to “empty” the air line, the on-car brake valves can detect a su...

Re: Railroad Thread

Adding crap to the discussion. I was joking, as air pressure actually applies the brakes, but zero PSI in the line triggers braking valves to send pressure in tanks on the cars to the brakes. (Others have said this). I agree with J that there’s roughly 90 PSI available. If brakes are applied and rel...
