USArmy & USNavy history

The Alco MRS-1's got a number from 2041 to 2123. Fifty units were equipped with a steam generator in the short hood. Their road numbers were prefixed with a 'B' (for boiler). They also had an alternate number 65-00xxx - 65-00xxx (given after transfer to the Navy). Navy numbering was straightforward: each new acquired unit got the next number from the list. The Alco MRS-1's had numbers ranging (at least) from 65-00543 up to 65-00616. (the 5 Navy EMD MRS-1's were numbered 65-00570 - 65-00574).

The five last Alco units in official service were all stationed at the Concord, California Naval Base. These were numbers 65-00612, 65-00613, 65-00614, 65-00616 and 65-00617. All MRS-1's are now gone from Concord NWS.

After the Alco MRS-1's were built, most were stored. A few, were lucky and got assigned to bases and put to work.

Alaska history

arr 1605Like the EMD MRS-1 units, some of the Alco units got a second job at the Alaska Railroad. In total 13 Alco units were transfered to the Alaska RR. Six units were aquired by the ARR in november 1974 (units B2049, B2050, B2053, B2054, B2055 and B2059) renumbered to 1601 - 1606.
In april 1975, a second delivery was done of 7 units (B2056, B2061, B2067, B2073, B2075, B2077 and B2100). The first 6 were renumbered to 1607 - 1612, while unit #2100 (ex USNavy 65-00586) only served for spare parts.
