ProgressiveRailroading.com: Virgin Trains selects Wabtec for PTC implementation

I know we've talked about this elsewhere.

Brief, fair-use quote:
Virgin Trains USA awarded Wabtec Corp. multiple contracts worth $120 million to implement positive train control (PTC) signaling and train control systems on the intercity passenger-rail service in Florida.

Under the contracts, Wabtec will install its Interoperable-Electronic Train Management System (I-ETMS®) PTC safety overlay in two phases.

In the first phase, Wabtec will install the system on a Virgin Trains’ 67-mile rail corridor between Miami and West Palm Beach. Work will include a back-office system and fitment of both freight and commuter locomotives.

Phase two entails the installation of I-ETMS along the West Palm Beach to Orlando rail corridor.

DARN IT JEFF! YOU BEAT ME TO THE PUNCH!!! :P

Well, hopefully this helps speed up PTC implementation along Birghtline, considering hearing that they cannot return to service without the implementation of some form of PTC. Any thoughts about WABTEC installing this system? I say as long as it can be installed sooner than later, and done correctly, the better.

I'm guessing they wanted to reduce the infrastructure costs on the new lines, as they already had ATC on the FEC mainline. I personally haven't heard great things about I-ETMS's ability to operate at high speeds, so I hope they're not making a mistake by doing this.

Are speeds of 110-125 mph high speeds? Amtrak on the NEC uses the same system and reaches maximum speeds 135-150 mph without problems.

Amtrak does not use IETMS on the NEC, it uses it’s proprietary ACSES for PTC on the corridor. The MTA commuter railroads use a variety of ACSES that is interoperable with Amtrak’s ACSES.

My understanding is that IETMS is oriented toward freight railroads, so the question about its propriety for higher speed passenger service is a good question (to which I don’t have the answer).

Long story short, ACSES is based on fixed beacons (“balises”) set within the track gauge, I-ETMS is based on GPS readings and track profile. Both are wirelessly operated, and both are fail-safe systems that can be overridden only by the dispatcher.

Theoretically, Wabtec would only take the Brightline contract if they could offer 125 mph service. The train speed shouldn’t matter that much.

Apparently Amtrak has installed I-ETMS on the corridor south of Philadelphia if the following report is true -

Perhaps one of the Amtrak engineers on the board can confirm or deny this.

ACSES cost a lttle more in the beginning but the system freight RRs pick need more realestate. ACSES does not require GPS or big antenna locations off the ROW. Denver is still having problems with airport line due to buildings blocking AGPS signals.

If you read the article I linked to you'd see that MARC is mentioned. I'm guessing it saves them money only having to install one PTC system on their diesel fleet. Their HHP8's would of course have ACSES.
