Watch out NJ transit. :lol:

Yes its good to have a train go up to 150 between stations that are only a mile or two apart. :lol:
NJT actually has stations that are less than a mile apart, there are a few that are only about a half mile apart. You can't even get up to 50mph and still stop at the station in that distance, let alone 150. :lol:
However it remains to be seen just how good or bad this new train will be. After all Bombardier is marketing this train on it's own. Hopefully they built it better than the Acela Express and learned from their mistakes. Also don't forget that unlike the Acela Express no one is pushing Bombardier to deliver this train on a schedule. Amtrak was pushing Bombardier very hard to deliver the Acela Express. Plus the jury is still out on just how much of the blame for the Acela Express is Bombardier's fault vs. how much of the blame for the design problems belongs to Amtrak's myriad of change orders.

Yes, thats a valid point, chances are this will be in better shape than the original for those reasons.
Is this basically an improved diesel-version of the Acela Express as far as the car set up where its difficult to add more cars?
I wonder what these trains would be like had Pullman and/or Budd been around to build them.
I guess with Budd it would've been an MU.

I honestly don't know. I suspect that they've since improved the tilting mechanism, such that you don't need a fixed consist but who knows. I would however hope that they made it easier, even if it's not a traditional coupler.
Yeah that's a little scary that she didn't know the answer to that question.Miami Joe said:
: The fact that she was unprepared for that question either means that there is or at least they suspect that there will be a problem, :unsure: or she and/or her staff are incompetent. :huh: Because unless you've been living in a cave for the last three months, that's all anyone mentions if you say Bombardier. I got the impression that this loco is being designed as a unit by itself and will not be part of a fixed car consist.
The passenger cars in service run at high speeds now on the corridor. Only the loco will tilt to allow high speed in curves and keep the G-forces low to the ground. This eliminates having to bank the curves like a racetrack.
I'm curious why a government office would get involved with private enterprise. I remember back around 1986, when Amtrak brought the ICE 2000 to Miami for the public to look at. It too, had tilt devices and I can't figure why the government would endorse a manufacturer and its product when it harms other vendors in the market.

Actually Joe, I'm under the impression that it's the passenger cars that tilt so as to reduce the forces on passengers.
That's how the Acela Express works, only the passenger cars tilt through the curves. The power cars do not tilt and in that regard operate just like any other engine on the tracks. That's one of the reasons for the two power car approach. The lead power car senses the curve and the onboard computer computes the angel of deflection needed for the passenger cars. The computer then signals each individual car to tilt at the proper moment and to the correct angle.
The trailing power car lets the computer know when the whole train is out of the curve and also helps in the correct timing of each cars tilt based upon it's own sensors.
