I was down there for the first time the other day, and I don't believe Ham flooded, or if it did, it wasn't nearly as deep as Trenton - Ham is on a hill (upward going east) and the top of the hill is at the old Millham tower). Its a slight hill, but a hill never the less.
If the Septa trains were parked on track 5 at Ham or better yet, east of ham on track 5, they probably would have been just fine. And even if there was water there, it would have gotten their wheels wet adn thats about it.
In Trenton station its easy to see how deep the water got, all the vegitation on side of the cut on the walls is dead from where the water was. It looks like it went even a lil higher than that, but where the water sat and laid for the longest time is where there is nothing left.
The signals and switches were working at Ham the other day, but not at Fair. Although I saw on NJ.com that Septa is back running into Trenton today. I wonder if they got the switches and signals back at Fair or if they are just turning all the trains at Ham?
