Sorry for the empty post--A little jittery cold here in  Helena--(mostly 
clear skies, -2F, 20 mph wind to bring wind chill down.) If it  warms up I 
might be able to catch a photo of MRL 332, former EL 3657  (?#) sitting NE of 
Helena (in the yard).  Internally it  has been upgraded to an SD45-2 now. It 
is the trial unit for the Hotstart  Auxiliary Power Units that MRL is 
considering putting in fleet-wide to reduce  fuel and emissions. Effectively, the 
EMD 645 shuts down (and its fuel guzzling  6-gallons per hour at idle) and 
the Hotstart APU (powered by a Yamar diesel at  an estimated 0.45 gph) starts 
to keep the engine water and oil warm, and the  batteries charged.  Unlike 
some of the SWs and GP9s, there is plenty of  room in the hood for the APUs. 
I suspect either tonight or tomorrow night they  should have a good 
demonstration of how it starts at -14 or the  predicted -18F on Monday night.
