I appreciate the respect, but your very own timetable disagrees with you. HSP-46 speeds Lite, Multiple Lite, and With train are 50, 50, and 90 respectively. I have deduced that this is why ACSES displays 90 in the cab on the corridor when MAS for MBTA equipment is 79mph. Interesting to note is that ACSES displays 80 in the cab in other locations where MAS is 79mph.
Sorry for the confusion. The OG question was the HSP's MAS....which is 103 mph per the MBTA Operating Instruction Book. We are restricted to those speeds you provided, by the Keolis S.I. book
As for the "80" vs "79" display, the Worcester ML has this issue, it is just another glitch in the coding that would have cost $$$ to go out and "correct" the transponders in the gauge, they just left it at 80. Should be 79 mph.
As for the 90 mph displayed on the ADU, I was told it was the "C" or "D" speed ratings to comply up and down the Shoreline, I'll inquire into that tomorrow. Doesn't matter today tho, MBTA trains operating over Amtrak territory are considered "B" trains now...yet our ACSES hasn't been updated to "B" speeds ......$$$
