As detailed in the February 2010 issue of TRAINS, ventilating exhaust from Mullan Pass tunnel has been a challenge since its completion in 1883. This sequence of photos, taken by TRAINS Art Director Tom Danneman, shows a BNSF haulage-rights coal train emerging from the tunnel with two helper sets assisting. It shows dramatically the problem of locomotive exhaust ventilation the tunnel faced before recent work.
