The Sprinter should do better in that role.*blinks* so SEPTA should pass over a locomotive in US commuter service (ALP46) for one in US intercity service (ACS64)?

And the SEPTA ALP-44 has a EPIC 3102 and does not have electric hold like the NJT ALP's.Any decent speed push pull express run will put out a cloud of brake dust braking into a station stop or into a speed restriction area. If the wind is right, it comes into the cars.
The SEPTA coaches have tread brakes only, no disc brakes. You can see them smoking on the Trenton Push Pull set sometimes.

It's like a first time ride on a train despite almost daily rides on the L.

lol.sammy2009 wrote:This should be snazzy to hear ....and see a model designed. Some people predicted this. So i guess Bombardier can make the other rail cars....and we need either two door-ends , or three door locations.The only difference between the SEPTA version and the AMTRAK version will be the road numbers and paint job.
