As of this morning, ACSES is live on the New Haven - Springfield Line.
I thought all that you needed was 110 capable cab signal to do so. ACSES was mandatory only over 125mph. I don't believe the 110 speed limit on the Empire Corridor was reduced either pending availability of ACSES.How have they been running at 110 for the past few months without ACSES?
That’s correct but I thought the rule was modified to now require PTC. Maybe it goes into effect when PTC does on the 31st.I thought all that you needed was 110 capable cab signal to do so.

I repeat: the bulletin that instituted ACSES rules on the territory only applies to Amtrak trains.From what I’ve heard locally they are operable on the CTrail commuter trains also.
Unless something changes, that rule won't take effect until the 31st.That’s correct but I thought the rule was modified to now require PTC. Maybe it goes into effect when PTC does on the 31st.
My understanding is CDOT elected to activate ACSES at the same time on their equipment even though not required to do so yet by the bulletin.I repeat: the bulletin that instituted ACSES rules on the territory only applies to Amtrak trains.
When you quoted my response about the rule taking effect until the 31st, it has nothing to do with ACSES rules being in effect. What you quoted has to do with exceeding 79mph without PTC. You are now conflating two different subject matters.My understanding is CDOT elected to activate ACSES at the same time on their equipment even though not required to do so yet by the bulletin.
That is what Amtrak should have done northbound before Frankford intersection. However Amtrak did not and no ACSES protection as it was thought that ACS-64s could not accelerate fast enough. Amtrak found out differently /RE; 188 !Curious about one thing - in the days before ACSES if you had a particularly risky curve or bridge that you wanted to protect with ATC/cab signals you would have to have a main line signal before the curve permanently in a slow aspect in order to enforce a lower speed at the curve correct?
You could use a fixed signal as you stated. You could also have a cab signal drop between the fixed signals to protect the restriction.Curious about one thing - in the days before ACSES if you had a particularly risky curve or bridge that you wanted to protect with ATC/cab signals you would have to have a main line signal before the curve permanently in a slow aspect in order to enforce a lower speed at the curve correct?
The Amtrak portion of Hudson line instituted ACSES rules on the same day as the SPG line.So, at the risk of veering off topic, I believe Amtrak doesn't have ACSES or PTC up on the Hudson Line yet?
Brings up a question. Has Amtrak replaced all the code line on their portion of the Judson line ?The Amtrak portion of Hudson line instituted ACSES rules on the same day as the SPG line.
It will be interesting. Our two local freight operators that operate over the SPG line, Pan Am and CSO, have not yet turned on their ACSES. Things will get even more interesting when they do.It is an industry problem. A lot of trains are taking delays due to PTC issues and as Amtrak706 stated, it will only get worse after 12/31, if something isn't done.
