This has extensively been mentioned before but I want to reiterate here: good riddance to the M2/4/6's. They were in horrible condition towards the end cosmetically and operationally. Floors were falling through, ceilings were prone to leaks, roaches, HVAC issues, cars dead in tow, bathrooms were shot, decades of slime and grime on the seats, etc. The M8's, while having have their short comings are of preference to the riding public and 99% of our T&E workforce, minus the 1% of the select few rail buffs.
I can certainly can agree with everything said here regarding the age and condition of these things. In short they don't owe the railroad anything. I never ever thought they would last this many years when they first came on the scene back in the early 70's. I thought they were supposed to be retired long before now but my friend (his identity has to remain private at this time) told me they were supposed to be all off the road before now. I only posted this one to bring it to the attention here of those who might be interested in this subject.
