But because SEPTA's least restrictive signal below clear is approach limited, which is displayed by default, they can only travel 45 mph over that stretch of track.bikentransit wrote:Hey!

SEPTA is the only Northeast Corridor operator that doesn't have ACSES or nine aspect cab signalling.

If there's a steady paycheck in it, I'll believe anything you say.

I tried looking around the control panel without being conspicuous (the engineer had left the cab door open before departing Trenton) but I couldn't see anything for displaying the higher cab speeds. Still, I thought NJT and MARC had both upgraded to Acses. And Metro North owns their own stretch of NEC so I wasn't even thinking about them.

MARC is also ACSES capable as they use the standard Amtrak cab signal units. Most MBTA units are also ACSES capable as ACSES is in service between Boston and Providence (again using the standard Amtrak cab display unit).

NJT MP20B's, ALP46A's and new dual modes have ACSES equipment installed but is sealed in the cut out position and is not functioning. The rest of their equipment has SES equipment but it is also cut out and sealed. They gave up on their own SES system and discontinued using it. SES was never compatible with Amtrak ACSES. I believe it was developed after the wreck at Secaucus in 96 as a form of PTC. It never worked well so was abandonded with the intention of adopting Amtrak's ACSES instead. When they will actually begin using ACSES is anyones guess.
I am surprised that the FRA would allow NJT to operate non-equipped units over track where ACSES is in service. The cab display units certainly support ACSES after the HDCS upgrade about 10 years ago. Down in SEPTA land Amtrak left track #1 south of RAGAN non-equipped for SEPTA"s non-equipped MU fleet.
I had the same question about the Vs and being able to display a Cab 80 aspect a while back, and in fact I wound up PMing Amtrak67ofAmerica about it. I had ridden the 3 prototype cars last February on 1256 out of Newark, and sitting immediately behind the "railfan window" noticed a flashing green Cab Speed aspect at Ragan leading to another Cab Speed aspect at the north end of the A extension (can't remember that interlocking name). We definitely did much more than Limited speed for sure.
Anyone know how that Cab 80 aspect is displayed on the Vs? The very few times I saw the CDU it was displaying traditional 4 aspect values like on the rest of the fleet.

Everyone is wrong on all accounts. PTC isn't being enforced yet by the fra. Only Amtrak an Amtrak rule book states that only Amtrak units are required to have the acses operable. Also track 1 south of Ragan to Bacon is indeed acses territory. It doesn't need to not be acses territory to support septa or anything that isn't acses equipped.

I have run the V's on test trains in NJ for 110 speed testing and I have seen the cab speed 80 signal displayed. I have to check the Slv operators manual because I seem to remember it being a speed display unit and not an aspect display unit but I'm qualified on so much equipment that I could be confusing it with something else. Other engineers have gotten the cab speed 80 code in the cab when diverting at Ruthby.

Where's Ruthby and from what are you diverting?
Patrick Boylan wrote:Where's Ruthby and from what are you diverting?RUTBY is an interlocking between Wilmington, Delaware and Newark Delaware. It was built when Septa started service to Newark. At Ruthby, you pick up "A" track, so you have a 4 track main line to Davis Interlocking, where Newark train station is located. This way, one train can approach the station while another departs.
