BLW 6-606A N XL L M4

Baldwin 606A Prime Movers were used in a few Baldwin prototypes.

RS-12, S-12

Recorded from a BLW S-12

This project is a normal idle version. It is an air throttle version. It has a single exhaust stack.

File also contains an "Isolation Switch" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be turned off to begin moving.

Another Mode is "Reverser In Center Position". When pressing F24 while stopped, the motor will more…

BLW 6-606SC N XL L M4

Baldwin 606SC and 606A Prime Movers were used in quite a few Baldwin prototypes.

DS-4-4-1000, RS-12, S-12, DRS-6-4-1000, DRS-4-4-1000, DR-6-2-1000, DT-6-6-2000, RT-624, DR-6-4-2000, DR-6-2-1000.

Though not quite correct the 606SC/606A Prime Mover sounds very similar to the 608SC/608A Prime movers This would be appropriate for:

DRS-6-4-1500, DRS-4-4-1500, DRS-6-6-1500, AS-416, AS-16, AS-616, DR-6-4-1500, DR-4-4-1500 and the RF-16(Sharknose).

BLW 8-608SC N XL L M4

The Baldwin AS-616 was a diesel-electric locomotive of the road switcher type rated at 1,600 horsepower (1,200 kW), that rode on three-axle trucks, having a C-C wheel arrangement.
Nineteen railroads bought 214 locomotives, and two railroads bought seven cabless B units.
Used in much the same manner as its four-axle counterpart, the Baldwin AS-16, though the six-motor design allowed better tractive effort at lower speeds.

File also contains an "Isolation Switch" Mode on F15 when Standing Still.
Pressing F15 while not moving will lower the prime mover and lock the motor. F15 must be more…

CAT 3608 DII N XL L M4

CP 4711 was rebuilt in 1988 with a Caterpillar 3608 prime mover. In 1998 this loco was sold to Minnesota Commercial where is still resides today wearing Road number 71.
This sound file is appropriate for the following locomotives: M636

Please note this file has both air and electric starters. Please research your prototype to be sure of which starter to use. Recorded from a MLW M-636 Minnesota Commercial #71. This project is a normal idle version. It has a single exhaust stack.

Cooper Bessemer 6-FW-6-LT N XL L M4

General Electric produced the 70-ton switcher as a complement to its 44-ton model. The idea behind the development of the 70-tonner was to provide a locomotive suitable for branch lines, switching and transfer service. To be a success, the locomotive had to satisfy certain criteria. It had to be:

• Light enough to run on 50-pound rail and light bridges,
• Powerful enough to move long cuts of cars in switching or road hauls.
• Fast enough to make light passenger runs.

The 44-tonner could more…

D&RGW K-27 2-8-2 N XL L M4

The K-27 is a class of 3 ft 0 in (914 mm) narrow gauge 2-8-2 steam locomotives built for the Denver and Rio Grande Railroad by the Baldwin Locomotive Works in 1903. Known by their nickname "Mudhens," they were the first and the most numerous of the four K classes of Rio Grande narrow gauge engines to be built. Of the original fleet of 15 locomotives, two survive to this day and operate on heritage railways in the United States.

Fifteen locomotives were built, originally class 125, they were more…

Detroit Diesel Dual 6-110 N XL L M4

Budd RDC
Detroit Diesel Dual 6cyl Prime Movers

The Budd Rail Diesel Car, RDC or Buddliner is a self-propelled diesel multiple unit (DMU) railcar. Between 1949 and 1962, 398 RDCs were built by the Budd Company of Philadelphia, Pennsylvania, United States. The cars were primarily adopted for passenger service in rural areas with low traffic density or in short-haul commuter service, and were less expensive to operate in this context than a traditional diesel locomotive-drawn train with coaches. more…

Dual ALCO 16-251C N XL L M4

The ALCO 251 prime mover was the most popular and abundant prime mover ever made by the company. While it proved to be quite successful, it sadly outlived its original manufacturer. ALCO closed their doors in 1969. The 251 prime mover is actually still available to purchase today from Fairbanks Morse for use in marine, generator and locomotive uses.

The ALCO Century 855 was ALCO’s most powerful diesel-electric locomotive. Powered by a pair of 16 cylinder ALCO 251C diesel engines, and rated more…

Dual CAT 8-D17000 N XL L M4

The GE 44-ton switcher is a 4-axle diesel-electric locomotive built by General Electric between 1940 and 1956. The locomotives were available with a choice of prime movers. Most were built with a pair of Caterpillar Inc.'s D17000 V8 180 horsepower (134 kW) engines. It was designed for industrial and light switching duties, often replacing steam locomotives that had previously been assigned these chores. This locomotive's specific 44-short ton weight was directly related to one of the more…
