Research by Scott Thomas
The order of SD40-2 that were delivered as T&P 816-839 during 1973 and 1974 was an interesting group.
UP ex MP SD40-2s, from UP 4115
After being delivered as T&P 816-839, they were all quickly renumbered to the T&P 3115 class later in 1974.
When the T&P was merged into the MP on 10/15/76, they were all officially renumbered as MP units with the same numbers on that 10/15/76 date.
