Colour-coding the train interiors would, of course, in principle limit what line the trains could run on, and thus reduce operational flexibility.
Indeed. Consider for a moment the current fleet. From what I've read, the H5s have run on both lines, the H6s were run only on the B-D line and the T1s were delivered to the YUS line but transferred to the B-D line and now, of course, run on the Sheppard line as well. Granted, as far as I can tell, once married pair is assigned to a carhouse, it won't move around the system except in unusual circumstances, so theoretically they could swap out interior features in a car to fit the line that it's running on. However, that would be costly and doesn't do much for the T1s that run on the Sheppard line that are shared with the YUS line.
According to Brad Ross, our favourite piece of the 1970s will be making its last run on the B-D line tomorrow AM.
"Run 64 leaving Greenwood eastbound to Kennedy at 7:27 AM. Then to Kipling, and back to Greenwood. One trip."
Sad. I knew the end was nigh as I was seeing fewer and fewer of them in service on the line. I was trying to take in as much as I could of each journey knowing that it
could be the last. However, I always thought that they would have stuck around a little bit longer. I think I'll miss the H6s the most when they're gone.
Well, it's now 9:36am, so I guess in a way that's the end of an era. This was the last of this type of train that, arguably, began with the H1s in the mid-60s. While the nomenclature lives on (for now) with the H5s and H6s, those have bigger differences than those between the H1 through H4 and have noticeably different body stylings.
