Our current collection of ETT's for the Northern Division is wonderful, but there is a gap between 1964 and 1975. By chance does anyone have an ETT for any of those years in between? I'm trying to narrow down what year the siding at Iantha was extended. In 64 it was listed as 44 cars long, and by 75 it was listed as 134 long. I need to ask Grandpa in case he remembers, but in case he doesn't I would like to narrow it down by ETT if possible.
