My thoughts:
It's interesting to note that most of the MP36 failures have occurred on the MILW district. Possibly because they have the most assigned there right now, although I admit that's oversimplifying it somewhat...
And speaking of assignments, there does appear to be SOME logic to the current arrangement, although I like Bones' idea better. Even so: Why is 211 still held captive at Western Ave, wandering on MDW, MDN, or NCS going on almost 2 years now? Did this unit originally come from RI? Anyone that knows, feel free to edify...
But anyway, on to the main event. Earlier this week, train 2121 (MDN, Dp CUS 1435, Arr FL 1608) with an MP36 on the point developed HEP trouble en-route, and wound up being over 20 min. into Fox Lake. Several other trains in both directions, due to late meets at Grayslake siding, as well as delayed turns of equipment at Deerfield (suffered by its follower 2123) were impacted as well. Eventually, 2121 became 2146 at Fox Lake, and upon it's tardy arrival at CUS, it picks up a "protector" locomotive before heading back out as 2145. But guess what? It picked up ANOTHER MP! I have heard of cases where 2 MP's were doubleheaded due to one having issues, but it's also been done
when spare F40's are available!. Now someone please, correct me if I'm wrong, but if you've got an MP that's been having HEP issues, why would you double-head it with another MP, when a perfectly fine F40 is available? That makes no sense at all. Again, maybe in this particular case there was no choice, since it occurred during rush hour, so I don't know for sure. But if it does turn out that more F40's are coming to Western Ave from 47th St., it probably can't happen soon enough. Be that as it may, however, it still must be noted that this latest incident does little to improve the performance and reliability reputation of the 400's at Western Ave, and it simultaneously enhances Bones' assertion that the competence level there may indeed leave a lot to be desired.
With regards to the imminent NCS and SWS expansions, 3 locomotives are being added to SWS, while 2 more are being added to NCS. Although Metra currently has a surplus of power which will handle these additional requirements, I do hope that the pool of extra locomotives isn't seriously diminished. Some shops seem to have more extra power than others, but ALL shops should have at least one or two tried and true EMD F40's laying around as protective power for it's diesel-hauled routes. Stick to what works.
OTOH, I personally, like the MP36's. The aerodynamic styling, along with the "lightning stripe" paint scheme combines to give Metra a more modern, futuristic, and progressive image, and as such, they have greatly enhanced my photo collection. It's a much nicer visual alternative to the reliable, but utilitarian and boring F40's, especially since the F40's can be so annoyingly ubiquitous at times, which is certainly the case in my neck of the woods along the UP-W, where absolutely no other passenger locomotive dares to tread. That said, I'm also grateful that my viewpoint is strictly from a railfan's perspective, indeed, I'm sure I'd feel a lot differently if I had to operate and/or maintain them. But if you're riding on a train with one of those as its power, and you're NOT riding on BNSF or RI, I'd have to cross my fingers, and hope that you can get where you're going on time!
(btw- For you F40C fans, anybody happen to catch the shot of 600 passing Rondout on page 51 in the August issue of Trains?)
