IMHO, I don't think using M1/3's for diesel coaches should be included in "Crazy Ideas". It's a great idea. The problem is the 21st Century LIRR. The planners on the LIRR are convinced that, whatever they did before was bad and everything that is done today is good. The thought of not having billions available to spend on their "dream" trains, and having to resort to recycling 150 or so out of the thousand MU's that are being replaced, is unthinkable
We get these stupid speeches about "if we do what we've always done, we'll get what we've always got", when we have to requalify and they tell this to new hires. That amongst other, nickle and dime slogans new people are subjected to.
I've been on the LIRR for a long time now, and everytime I hear this, I'm wondering what exactly they think we did wrong years ago when we were a real railroad.
The LIRR I hired on to, would have, in a pinch, used a Yard Switcher to pull a train, just to fulfill the schedule. Today, the modern, sophisticated LIRR will cancel it if one of those rolling monstrosities they call locomotives aren't available.
I couldn't imagine the new LIRR ever recycling used MU's for diesel coaches. Is it a bad idea..no. But, it would change the symetric look of their fleet and to have some cars double-deckers and some single level mixed together in one train..gasp..they would pass out at Hillside at the thought!
