SP S12 page: T&NO FM/Baldwin Swap
T&NO FM/Baldwin Swap:
The SP made the decision to keep all of its FM switchers assigned to the Pacific Lines and diverted two FM xxxx units originally assigned as T&NO 119-120 to SP 1575-1576 and in return sent two Baldwin S12 units SP 1498 & 1505 to become T&NO 121-122. These units were renumbered as SP 2124-2125 in the 1965 system renumbering.

| SP 1498 | T&NO 121 | SP 2124 |
| SP 1505 | T&NO 122 | SP 2125 |
