EMD 12-567C 2EXH NT N XL L M4

The SW1200 was the third model of 1200 hp SW series switchers built by EMD. It was a successor to the SW7 and SW9. Compared to its direct predecessor, the SW9, the SW1200 differed in that it used the improved and more reliable 567C engine, compared to the SW9's 567B engine. Late SW1200s built in 1966 were instead built with the 567E 12-cylinder engine. Most of the locomotive's external features were unchanged from the SW9, making distinguishing between the two models difficult.[1]

EMD 12-645E 2EXH NT Ed3 N XL L M4

The EMD 645 family of diesel engines were designed and manufactured by the Electro-Motive Division of General Motors. The 645 series was an evolution of the earlier 567 series and a precursor to the later 710 series. The 645 series engines entered production in 1965. All 645 engines utilize forced induction, with either a Roots blower or a turbocharger. The 645 series has a maximum engine speed of between 900 and 950 revolutions per minute (rpm), an increase over the 800 to 900 rpm maximum more…

ALCO 6-539T Ed2 N XL L M4

The ALCO 539 engine was developed in response to the perceived drawback that ALCO's line of diesel switchers had a restricted field of vision because of the high hood. Both Baldwin and EMC were offering diesel switchers with a lower engine hood that the trainmen could see over.

The 539T was equipped with the Buchi turbocharger, being made under license by the Elliott Manufacturing Company of Jeannette, Pennsylvania. The first 539T engines were used in S-2 switchers and DL-105 passenger more…

EMD 16-645D3A T N XL L M4

Between 1981 and 1983 Chessie rebuilt 67 EMD GP30 locomotives.
These were B&O and C&O GP30 units that went through Chessie's rebuilding program at both the Huntington and Cumberland shops. After rebuilding Chessie did not renumber the units, but CSX decided to give them their own number series once they took ownership.

GP-30Ms were internally rewired with some modular components similar to Dash 2 units. They also recieved new IDAC wheel slip control, D77 traction motors, and cab heaters. The more…

GE 12-7FDL12F42 N XL L M4

ATSF had on going rebuild programs for U-boats. After the success of the SF30C, Cleburne took aim at U23B's for rebuilding next. The SF30B is a one of a kind rebuild, which now belongs to Minnesota Commercial. ATSF saw it more effective to purchase new locomotives. The SF30B had many upgrades, the unit's horsepower was increased from 2300 to 3000 hp, as the Cleburne Shops installed a General Electric 7FDL-12F30UX prime mover. The electric systems were modified to Dash 7 standards, and Sentry more…

EMD 16-710G3C LATE EXH T Ed2 N XL L M4

The EMD 710 is a line of diesel engines built by Electro-Motive Diesel (EMD). Introduced in 1985, the 710 series replaced the earlier EMD 645 series. Since its introduction, EMD has continually upgraded the 710G diesel engine. Power output has increased from 3,800 horsepower on 1985's 16-710G3A to 4,500 horsepower on 2012's 16-710G3C-T2. Over the production span of certain locomotive models, upgraded engine models have been fitted when these became available. For example, an early 1994-built more…

GE 16-7FDL16H18 LATE EXH N XL L M4

The GE FDL-16 prime mover was first used in 1959 in the General Electric U25B locomotive. Over the years little changed in terms of sound until the "Dash-8" series of GE locomotives was introduced. Known for their throaty chug and shaft driven compressor (rather than the more modern “Whoop” electric compressor). There was an interim period following the "U Boats" that began the era in GE called the "Dash-7s". During this time many locos started receiving exhaust silencers and the shape of the more…

GE 8-7FDL8D2 N XL L M4

The GE U18B was introduced by GE as a branch line roadswitcher in 1973. Easy to spot due to its relatively short length — 54 ft 8 in (16.66 m) — it was the only North American locomotive powered by the 8-cylinder FDL engine.

There were some export locomotives built with this prime mover:
SG10B, U15C, U17C, U20C, and the C18-7i

The U18B was not well recieved as only 5 railroads bought the locomotive, with one railroad only purchasing 1 unit, for total of 163 units produced. The Seaboard Coast more…
