It'll be a long time before SEPTA has all high-level platforms. Would there be structural issues in cutting the side sills to provide low-level boarding?

If SEPTA is interested in buying used rolling stock that needs some work, but could serve a long life, Exo's MR-90s might be a good starting point to start replacing the Silverliner IVs, which are soldiering on but are clearly past their prime.

Electric MU's work a lot better on a railroad like SEPTA where the stations are very closely spaced on some lines and you need faster acceleration and deceleration to maintain the schedule.Considering how heavy these EMUs will be, I doubt the normal benefits of having MU operation will hold true.

I think that the ACS-64s with 3 Bomber coaches and a control car could be used off peak, but they need to be used in specific areas: Wilmington/Newark line, Trenton line, and Paoli-Thorndale line.

When SEPTA was running the all-day push-pull train, it seemed to have more issues tied to touching so many lines throughout the day and crew issues than actual acceleration problems. I suspect if they had assigned it to run consistently on one line it would have done just was well as the EMUs.Head-end View wrote: ↑Mon Feb 03, 2020 9:41 pm MattW, locomotives work better on lines with some distance between stations.

It didn't really have trouble making the schedule for most of the day, but it was all too easy for delays to cascade if something went wrong. I don't think it's an experiment they'll repeat.It should be noted that SEPTA had a hard time running that trainset all day even with EMUs. In one of the last schedule changes, the morning and midday runs were separated from the afternoon and evening runs. I suspect if you ran the 4 car set on the afternoon and evening runs (30th Street to Warminster, Warminster to Thorndale, Thorndale to Doylestown, and Doylestown to Malvern) the performance would be comparable to EMUs.
