It turns out, the Type-9 design flaw that I reported on this thread (Page 38, 2nd-to-last post) is worse than I originally reported.
On Friday, 15-Feb-19, with stopwatch in hand, I went for a few LRV rides. The front door mirror on the Type-9s is only part of the problem. On the Type-9s, the front door takes 8 seconds to open and ten seconds to close before the train can move. This includes the time for the mirror to unfold/unfold as well as the door opening procedure. By contrast, the Type-7s and the Type-8s take two seconds to open and two seconds to close. That’s fourteen extra seconds at each and every stop. With eighteen stops from Park to Riverside, that’s more than four minutes. Of course, if one is a commuter who goes both ways, that’s eight minutes a day or forty minutes a week.
Because the train is undergoing testing, there is a supervisor on the train in addition to the motorman. When I reported my findings to the supervisor, he was totally unconcerned.
But wait, there’s more. When I went online about 10:40, car 3900 was inbound at Copley. The next Riverside car inbound was one minute behind them. I don’t know when either car left Riverside, but read on.
When I went online at 11:21, car 3900 was at Fenway, outbound. Best case, I figured 30 minutes to Riverside at current scheduled times, and another five minutes back to Waban, which is where I get on the train. When I arrived at the station at 11:55, car 3900 was already at the station, but he was outbound. It had taken him 34 minutes to go ten stops, or 3.4 minutes per stop. Back in 1959, the schedule was 2.0 minutes per stop. This was 70% longer than 1959, and 33% longer than current time tables. After 3900 left for Riverside, two trains followed within six minutes.
After I parked my car and was waiting for 3900 inbound, a type7/8 train passed Waban at 12:07. One minute later, at 12:08, car 3900 picked me up. Because we were right behind the previous train, there were no passengers at Eliot, Newton Highlands, or Newton Center. We saved 54 seconds because the doors did not open. I wonder if this was intentional. When we arrived at Copley at 12:42, it had taken us 34 minutes to go 13 stops, or 2.6 minutes per stop. Despite the 54 second savings, we still took longer than the scheduled 2.5 minutes per stop.
