As for the F-3 production in New Jersey, this from the McComas-Tuohy on the F-3's, this is located on page 57. Further on page 56 it states that Lenny Dean (picture included) was the force behind bringing back the F-3's.
"Until the Rio Grande (74 and 75), all the F-3's had been made in New Jersey. The Rio Grande was the first F-3 to be made entirely in Mt. Clemmens, although the shells had always been molded there"
This would indicate that the B & O, Canadian Pacific, and Amtrak were made in Hillside.
