>>1597224Boston to Worcester MBTA has to slow down to about this speed 3/4 of the way to Worcester. Something about the section being created for freight not passengers and the lines being made of 1/4 mile welded sections that heat up. Interesting ride you notice when it slows down.
Funny too is how the trains used I think are EMD f40's that were originally freight based with freight generators made updated into passenger trains.
