How do they survive?

After seen many D&RGW DVD's I wonder, how do the crew survive in the tunnels? There are smoke everywhere. The cab's must be sealed, right? In one of the DVD's I saw the crew open all windows after coming out of a tunnel.

They probably had respirators, supplied with main reservoir air from a valve on the backhead.

I don't think I would want to breathe main reservoir air much more than smoke unless it was seriously filtered.  I would like to know just what engineers and firemen did do besides put a cloth over their face.

It's not really a problem these days. Just close the windows. Some railroads like Montana Rail Link do supply oxygen masks though just in case.

That's exactly why the Southern Pacific used cab-forward locomotives on the Overland Route. Diesel locomotive cabs are fairly enclosed, steam locomotive cabs generally not--so yes, people were exposed to lots of coal smoke. Unpleasant, yes, but generally survivable.

The 14 tunnels asending the front range were quite short, wheras the long Moffet Tunnel had huge blowers. Tennesee Pass I don't know.

It was a problem on the Denver & South Park's infamous 'Alpine' tunnel.

They were real men...and they liked it.
