A decade ago DelDOT installed an 80 mph crossover near Newark station. A modern nine aspect system is needed to display CAB 80 to take it at full speed. 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! Another quick question, since the Silverliner V cars are brand new, are they going to be compliant with the new system, or at least easier to upgrade?Doesn't all of SEPTA's equipment (including the Vs) have to work with ACSES to run on the NEC?

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

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).

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.
