Caption: CN 4138 is the relief power for CN 595 - the Huntsville roadswitcher - this week, filling in for the usual 4132 while the latter is getting routine maintenance. 4138 still has the remains of the "AR Illinois" logo on its nose as applied for the movie "The Wrong Guy" with Dave Foley and Jennifer Tilly released back in 1997. I've heard people erroneously call this Geep the "40 unit" or the "AP unit" as missing paint/decal from the logo where access panels have been replaced over the years could make someone not familiar with the back story mistake it for either of those. I even had a CN foreman telling me a few years back on another of its relief missions - that time while 4136 was the "home" power for 595, "there's an IC unit down at Martins" because the Illinois lettering had him a tad confused. 4138 is seen here on the back track at Martins, about to back up the spur to the Panolam facility located there.
