Northern Division ETT 3, January 1, 1975 from the Richard E Napper Memorial Collection
Interestingly, there is a restriction on engine consists in this timetable that states from Leeds to Willard ( the Clinton sub ) only GP7s are allowed.
This also appears in timetable 3A.
Generally the bridges are the restriction, sometimes to upgrade a bridge only reqiuires minor repairs. Like during the late 70's we filled a bunch of bridges from Miami, Ok to Ft Scott to upgrade the line for heavier tonnages. I ran the Dozer on that project. When these lines were built they used a 100 year flood plain map for the bridges, which became obsolete when the river management came into effect in the late 60's.
For the Clinton sub, timetable 3A would have been shortly before the trestle on the north end of Blairstown burned. ( if I remember right, that was in the summer of 1976 ). The trestle was never rebuilt.
As for why the notation is interesting, in the 1960s, trains 58 and 59 ( at least ) had VO1000s assigned to them. Timetable 3 shows both the remaining ( repowered ) VO1000s and the GP7s with a bridge class of 39.5. Everything else ( except the Blakeley Island switcher (11) ) had a higher bridge class.
Separate names with a comma.
