Montana Rail Link Montana Rail Link ( reporting mark MRL ) (now operated by BNSF as the MRL Subdivision) was a privately held Class II railroad in the United States . It operated on trackage originally built by the Northern Pacific Railway and leased from its successor BNSF Railway . MRL was a unit of The Washington Companies and

1624-601: The warbonnet , and were redesignated SDF45 s. Electrically they were upgraded to SD45-2 standards. Mechanically, they were re-geared from 59:18 to 60:17, reducing their top speed from 89 to 83 mph (143 to 134 km/h). In the mid 1980s Santa Fe again re-geared them - this time to 62:15 for 71 mph (114 km/h). MotivePower used ex-ATSF 5989 as an EPA Tier-I emissions test bed in 2002. Metra in Chicago had ordered 27 MP36PH-3 passenger locomotives for commuter service. To test their emissions, 5989's 20-645-E3

2072-472: The forty F45s came in the blue and yellow freight colors. The second order of F45s were equipped with steam lines so that they could be used as trailing units on passenger consists. Great Northern (GN) ordered an initial lot of six, for 1969 delivery. These were numbered immediately following a previous lot of SD45s . Another lot of eight was ordered before the first six arrived. GN ordered twelve more for 1970 delivery - they were to be numbered 441-452 - but

2128-523: The fuselages fell down an embankment, with two reaching the Clark Fork River . The six fuselages were recovered and scrapped within the month. On the morning of Sunday, April 2, 2023, a westbound MRL freight train derailed at Quinn's Hot Springs Resort in Paradise, Montana . About 25 cars derailed, including cases of canned and bottled beer, clay powder and one with highly flammable gas (alternately described as butane or propane); some cars tumbled into

2184-704: The locomotive was eventually sold to another private owner, and the money that was raised was used to restore SDP40F #644. It currently remains stored in a rail yard in Airway Heights, Washington . Former Santa Fe #5989 was used as a test bed by MotivePower Inc. until 2021. It is set to be restored to the "Kodachrome" scheme, with the hope that it will be eventually sent to a museum.

2744-499: The usual D-D consist by 300 hp (220 kW) (with one fewer prime-mover than a usual D-D consist, thereby significantly improving reliability and dramatically reducing maintenance). Although the D-D arrangement is associated with twin-prime-mover locomotives of high power, this does not mean a D-D with a single high-power prime mover may be built in the future, nor does it exclude two-truck, eight-axle electric locomotive. The EMD DDM45

2800-540: The weight of the locomotive more evenly over the track and counteracts the tendency of trucks to oscillate at high speeds, which is a problem with two axle trucks. The idler wheels may be smaller than the powered wheels. Examples of locomotives with this wheel arrangement include the EMD E-units and ALCO PAs , which were high speed passenger locomotives, and the dual service FM Erie-built . BNSF took delivery of ES44C4 locomotives with this type of truck in 2009. In

2856-572: Was an SDP45 wrapped in a full-width cowl carbody, the new F45 was essentially an SD45 given the same treatment. Where the Santa Fe requested a full-width carbody for aesthetics, the Great Northern saw an opportunity to protect crews from the dangers of winter operation in northern climates. The Santa Fe ordered two lots of twenty each, for 1968 delivery. The FP45s were delivered in Santa Fe's red, yellow and silver warbonnet colors,
