Tunnel motors were variations of the SD40-2 and SD45-2 that had air intakes in the back bottom of the locomotive instead of on top. This was necessary because of over heating problems occurred when you have a string of locomotives slugging through a long tunnel and they are all drawing hot air that is trapped in the tunnel. The tunnel motor variety drew cool air from the bottom of the tunnel. The DRGW and the Southern Pacific were the only buyers of the tunnel motor but some ended up in UP armor yellow during the end of their careers.
The unit the CRRM acquired was the D&RGW 5401.
