That wasn't a "catalog"... it resembled more of a "pamphlet". All 8 pages of it! 
The small size of the catalog is probably the main reason I think it's realistic to try to collect everything that was offered.
I would not recommend any of the locomotives to an operator, they just weren't constructed that well.
By the way, the 1968 catalog had even less. Only one set was offered. There were two steam engines, and no diesels. On the positive side, one of those two engines was the 736 Berkshire.
There was no catalog in 1967.
