Yeah, it makes sense to me that both 270 ppm codes would be introduced for LIRR compatibility. I just have yet to find and example where 270/270...
One would have to see the signal control plans for the railroad to confirm this, but as far as I know, CAB SPEED 60 (270 ppm) is indeed used...
This article describes the cab signal progression I mentioned above....
Yes, MBTA uses an ADU that can display all 9 cab signals (plus stop for ACSES) as originally specified by Amtrak. I have not noticed the “TPP”...
See my posts above, but to summarize, the only services from NYP that prototypically need an ALP-45DP would be the services to Bay Head or...
The same goes for most midtown direct trains going to Dover or Summit (though these would probably go in the non-playable category since they...
Here’s my 2 cents on NJCL services: At least on the weekdays, the only trains required to have dual modes would be the 3300 series trains that go...
Thanks for the response, Brandon! I am happy to hear you are still involved in these potential fixes for Boston Sprinter. The route in its...
With the renewed interest generated by a new AC electrified route based in the USA, I wanted to give the devs some feedback on Signaling/Safety...
I agree with the general sentiment that this is partially an issue with how the dispatcher works. It simply does not make sense to have an Amtrak...
Great to hear and thanks to you and the rest of the team for keeping track of these points! These were the items that caught my attention, but I...
I have noticed similar behavior with the regular services too approaching Boston (Amtrak trains from Back Bay). It seems that the dispatcher...
Update: For Item (7) above, I now realize that the Stoughton Branch is NORAC rule 562 territory (no fixed ABS signals) - so we should have more...
After watching the last DTG stream, I understand that the next logical improvement for the route from Boston to Providence will be to address the...
This is a relatively small detail, but I thought it was worth mentioning. For hand thrown switches, the target (the red and green banner) should...
I should also add that for MBTA, ATC should enforce a limit of 90 mph for both the "90" and "MAS" balloons when either is lit. I am not sure if...
Some more points: 1.9 miles north of Sharon, there are two floating "DS" or Dead Section signs. I am assuming, these should be attached to the...
Alert curve! That’s the terminology I was looking for. What you get is a penalty brake if you fail to acknowledge the downgrade from ACSES or...
Brandon can probably correct me if I am wrong here, but the way ACSES should work is that you are already slowing down before the ADU changes to a...
Gotcha, I see no issues with that. As far as I can recall, in recent past, they kept the legacy AM cab signal for all turnouts at the distant and...
Thanks! I figured this was likely the case. The whole approach limited vs approach medium thing can certainly make things a bit more complicated....
Apologies if these have already been mentioned before, but here some points I’ve seen so far: For the alerter in the MBTA F40 cab, why does the...
