HotWater and Railbaron --
Thank you very much for the veery interesting and informative replies. Didn’t think about trailing units -- and DPUs, if any -- and the dirty air they cannot avoid inhaling.
So -- if you are the engineer on a really heavy train going west over Donner, you're going to have a really hard time getting through the Big Hole without stalling, right? And there really is no way to keep all the trailng unis and DPUs (if any) from inhaling dirty air, is there?
I eally feel bad for the hapless conductors who work with engineers who do not use good judgment about going into tunnels too slowly. That could be fatal to both f them!
Bring back tunnel motors! Or -- operate all railroads with eletric locomotives. The Milwaukee Road had the right idea, but they were a century ahead of the rest of the RR industry. Yes, I know -- that would be extremely expensive.
Do electric-powered locomotives pulling heavy freights through long tunnels ever have problems caused by overheating? TIA!
