Coming from someone hailing from an agency where we retired (officially) 44 year old cars yesterday, I can see where the nostalgia fanatics are coming from. Also coming from an agency who have spent $1.2 Billion on our NTT cars, I can see why foamers are ecstatic and upset about them.
I get excited whenever I come to NY to see your collection of cars. Honestly, my rule applies that 'as long as the darn things work, I'm thankful...' I won't knock on the foamers of the old school because honestly we'll all miss them when they're gone, scrapped, or reefed. And the NTT's aren't going away anytime soon.
Let's all agree that, at least, the darn trains work, regardless of the train line, and at least we're still alive to see them work hard (or hardly working).
