• Amtrak Gateway Tunnels

  • This forum will be for issues that don't belong specifically to one NYC area transit agency, but several. For instance, intra-MTA proposals or MTA-wide issues, which may involve both Metro-North Railroad (MNRR) and the Long Island Railroad (LIRR). Other intra-agency examples: through running such as the now discontinued MNRR-NJT Meadowlands special. Topics which only concern one operating agency should remain in their respective forums.

I get a real sinking feeling whenever I hear about the desire to fix the tunnels first. IMO go ahead with the fixing of the old tunnel bores but do not delay one hour longer before starting the new tunnel bores. What if a mistake is made putting one of the old tunnels out of service for a year or more ?

Then of course the possibility although not big is what happens if another "Sandy" comes along. Another flooding of the old bores could be disastrous. Does anyone know if some kind of flood gate is now in place ?

The Gateway Development Commission announced in March that Amtrak has awarded a contract and work has begun on behalf of the Gateway program to relocate utilities out of the future path of the third and last section of the Hudson Yards Concrete Casing in Manhattan, N.Y., a part of the Hudson Tunnel Project.

The commission is a partnership made up of the states of New York and New Jersey and Amtrak.

The $25 million early work project is the latest step in preparing for the full construction of the new Hudson River Tunnel and rehabilitation of the existing tunnel. The advance construction project will create jobs and provide an economic boost as the region continues to work through the COVID-19 crisis.
...
Planned in collaboration with the Long Island Railroad (LIRR) and its related companies, the utility relocation project involving LIRR's Emergency Services Building is a critical path activity that allows future construction of the concrete casing itself. The advancement of utility relocation was a key recommendation received from the private sector during the Gateway Partners' Request for Information process to reduce project risks and unknowns during full construction. The development of the future construction of the final section of the concrete casing is continuing.

Somehow I missed this. Mostly just a press release but:

Pull quote:
The Biden Administration has announced that a “critical milestone” in the Gateway Tunnel Project will be achieved in May—completion of the Final Environmental Impact Statement (FEIS) and the Record of Decision (ROD).

Read the last few lines .... Translation: "As soon as we got into office we told them to get this wrapped up as quickly as possible."

Pretty clear indication there what's going to happen once the infrastructure legislation goes through.

So as I was looking through NJ Transit's current schedule to respond to an Amtrak thread, I found something odd.

7am hour (rush hour) to NY Penn... a few trains were coming in two minutes apart.

Wait a minute... isn't the Hudson River tunnels max 12 trains an hour per tube? That's not right. That's more like 30. That the... can someone explain this?

I don't have a reference handy, however I want to say that for at least part of the rush both tunnels are operating in the same direction.

The maximum is 24 trains one way per hour per tube, for a total of 48 trains, 24 in each direction, with both tubes operating. If there is only one tube in operation, the total of 48 bidirectional trains is reduced to 12 per hour.

Okay, that makes more sense. I was led to believe it was 24 per hour combined.

Just to be clear this is definitely not the case.

Good to know. I probably misread something a few years ago and got that stuck in my head.

The Long Island does that on the two main tracks between Queens Village and Hicksville, resulting in a gap of over an hour with no eastbound trains in the morning and no westbounds in the evening, which may be the situation you read about. (The problem is now being corrected by the addition of a third track together with grade-crossing elimination, a project begun at least as early as 1990 and scheduled to be completed later this year. They say all things come to him who waits ... )

Hopefully they'll keep at least one track open for the reverse commute, but I have a feeling that will not happen in the future. (I also think they need to three-track the Babylon branch, but that's getting off-topic)
