How would they be able to fix the catenary if they have trains going by on the track the ET crews would use for access to said broken catenary?I didn't think of that. I guess I'll stick to selling tickets.

That 5 pount bag is already pretty full at Portal every day and we all know how bad it smells. Last thing you need is a disabled train on the High-Line between Portal and Swift at 4pm.At 11:54am, Portal Bridge opened for a test and when they closed the bridge, they were unable to close the catenary.Why didn't they just issue "drop pantograph" orders for Portal, and let the trains go.

Reading back, it's easy to understand that both tracks were affected and that when they did fix the first track, it was returned to service.

it seems its a lot more hassle to deal with connecting rails on a swinging bridge than with a lift bridge).I've operated all three types of railroad bridges, lift, swing and bascule, and found them all equally easy to operate. After you land the swing bridge, line it up, stick in the wedges, lock it, and drop the miter rails; you can take off the derails, raise the smash boards, and pull up the signals. At Portal they have the additional step of running the catenary out. Its on a trolley that runs in and out; at least it used to be. If a miter rail comes down on top of its fixed half, you might have to bang it with something, so it will flop down, into place.
philipmartin wrote:I wasn't really serious about "drop pantograph" orders for Portal, because of the possibility of tying up the high line. I don't even know if they are still in Amtrak's electrical operating instructions. But I know that they used to be because I'm looking at an Amtrak book dated 1979/1984. Earlier the same day that we are talking about, 3223 had trouble getting his pantograph up, standing in front of me at Middletown.Huh, The book from 1979/1984 is the same today????

They converted the Delair bridge down near Philly to a lift bridge after all, and my understanding is that it was more reliable after that as well.The Delair Bridge was converted to a lift span by the Army Corps of Engineers to allow ships headed up the Delaware River to the new U. S. Steel mill at Fairless, PA. The lift span created a larger opening than the older rotating span. The PRR didn't have to pay for this so they went along with it, remember that at this time PRR was losing money.

Even though the Delair's lift span is younger than the bridges being discussed in North Jersey it still has its problems. Just today after an opening the AC Line dispatcher was unable to get a signal for a train to cross the bridge because he was unable to reach the CSAO train dispatcher in order for CSAO to lock down their side of the bridge. Other times they can't get the locks to apply/remove mechanically or the bridge to close properly.
