To add to this, I want to latch onto the FRA PTC-by-2015 mandate:
What is preventing the MBTA/MassDOT from getting FRA certification and deploying ECTS, other than GSM frequency requirements, existing deployment of Amtrak's reinvent-the-wheel ACSES along the Providence Line, the sheer capital cost of implementation?
Have there been any recent attempts to even look into signal modernisation studies by MassDOT that have entirely flown under my radar in the past 4 years?
While I think a technical exploration of how signal, train control, and train protection systems would benefit the commuter rail is more suited to a conversation over at the railroad.net forums, I feel like a lot of the conversation gets mired in how it can't happen.
1) Because they are a founding member of the ACSES consortium and committed to it way back in 2001 with all the other NEC-sharing commuter railroads to deploy it on their equipment. That was before the PTC mandate so it wasn't expected at the time that it would go systemwide. It was, however, expected that the 3 Amtrak routes shared with the system--Lake Shore Limited/Inland Route on the Worcester Line and Downeaster on Lowell/Haverhill--would get it because of Amtrak. They picked it because they wanted it, were going to use it, and because it aligned them better as beneficiaries of the Amtrak funding spigot.
2) The F40PH locomotives being retired are the last pieces of equipment not equipped for ACSES. They're 100% equipped and paid-for in the fleet after 12 years of continuous installing. That significantly reduces the overall cost of deployment since the vehicles are all set. Make a break for a wireless system and they start from square one. And have to have equipment installed for BOTH systems.
3) Likewise, the entire southside ops staff is trained on it because every single Providence, Stoughton, Franklin, and Needham train must use it while on the NEC. No training necessary except for the northside crews. The only big expertise gap they have to close is at central dispatch, because right now it's the Amtrak dispatcher that controls all the PTC'd track...not T central ops.
3) ACSES works very well. It's proven nearly bulletproof after 12 years in-service. The Amtrak crews who post on RR.net are pretty much universally: "Just trust on on this: it...just...works."
4) The main reason the PTC mandate is collapsing on itself is because of the wireless systems. Lawmakers thought..."Oh, everything's wireless today! Shiny tech! This will be great." Only securing all the requisite wireless bandwidth has been nightmarishly difficult, to point where they still haven't got details settled allowing mass installations to begin. And because it's wireless your trains only move right when there's reception. Get a drop-out...train must crawl to a halt. Have poor reception coverage...must add new receivers you didn't think you'd need to. ACSES just piggybacks on the cab signals that have been there for 90 years in some places. Fixed hardware = max reliability. East coast is waaaaaaaaaay ahead of the rest of the country on being able to meet the deadline. The T is the only ACSES-member commuter railroad that is off-target and will need more than a year or two's deadline extension to wrap up.
5) It is cheap where you do have the pre-existing cab signals. It's only costing $8M in the stated budget line item to slap ACSES on top of the cab signals on the Springfield Line upgrades when all the other stuff is completed. That's ultimately 60 miles of double-track. It's very inexpensive for the T to do the installation on Fairmount, Stoughton, Middleboro, Greenbush, Kingston/Plymouth, and the Framingham-Worcester half of the Worcester Line where there are pre-existing cab signals. Price out the track miles from that Springfield Line figure and it's really not bad. The big hurdle is getting southside central control equipped to dispatch it. And that's where they've done bupkis.
6) It's not
awfully expensive to do when you have the right kind of wayside signals pre-existing. The lines that have continuous track circuits that can sense the trains are set up to have cab signals slapped on top as the second layer, then ACSES slapped on top as the third layer. The Fitchburg upgrades are doing this and can have the extra layers added later. So are the Vermonter upgrades out west. The Newburyport Branch past North Beverly has this. Franklin and Needham have this. Haverhill/Reading Line from Somerville to Oak Grove and Reading to Wilmington have this. The Wildcat Branch has this. It's the lines that have old unidirectional Automatic Block Signals or no continuous track circuits (i.e. signals relayed by telephone pole instead of through the rails) that can't get retrofitted and require total tear-out/rebuild. Worcester Line to Framingham. Lowell Line to Wilmington and I think in immediate vicinity of Lowell station. Haverhill/Reading between Oak Grove and Reading + Wilmington Jct. to Haverhill. Most/all of the Eastern Route mainline. All of the Rockport Line. That's where they are in a world of hurt and have about 9 figures in catching up to do that are unfunded, unscheduled, un-discussed. In part because they are so far behind funding and scheduling their deployments in the easy spots.
So...in a nutshell, it's cheaper and faster for them to just finish the job with the bulletproof system they're a decade-experienced using and ready to deploy cheaply on at least two-thirds of the southside than it is to supplement with the wireless that's so bogged down by unsettled spectrum details nobody's 100% sure it'll work without years on end of debugging. It's not about boondoggle vs. non-boondoggle technologies. What they've adopted is way, way more straightforward than the rest of the non-NEC tethered country has to use.
Their problem is delinquent planning and nearly no resources devoted to deployment save for nebulous "studies" items of $1-2M in the budget. Metro North/State of CT, Long Island RR, NJ Transit, SEPTA, and MARC have been nose-to-grindstone behind the scenes for the last 5 years getting ready. And are ready to start mass deploying. Granted, they started with more cab signaled lines than the T did. But they're gonna make their deadlines when it's not even certain the T is going to have done a damn thing by deadline with their 5-1/2 cab signaled southside lines that are ready for the finishing touches.
Not going too far off-topic here, but this goes to the confused priorities that the money is pouring into amenities while they're risking serious sanctions for blowing law-mandated investments. Both this and their stalled ADA compliance.
