The EMD GP22ECO is a 2,150 hp (1,600 kW) B-B road switcher diesel-electric locomotive rebuilt by Electro-Motive Diesel and Norfolk Southern's Juniata Shops. Initially EMD built two GP22ECO demonstrators, one based on a GP9 and one based on a GP40,[1] but thus far all orders have been for conversions based on EMD GP40 and EMD GP40-2 series locomotives. The rebuild involves replacing the existing prime mover with an EPA Tier-II-compliant turbocharged V8 710G3A, with Electronic fuel injection. The more…

EMD 20-710G3B LATE EXH T Ed2 N XL L M4

The SD80MAC is a 5000 horsepower C-C diesel-electric locomotive. The SD80MAC uses a 20 cylinder version of EMD's 710G prime mover,formally known as the V-20 710G3B-ES and is the first diesel locomotive to use a 20-cylinder engine since the SD45/SD45-2. The SD80MAC introduced a wide radiator housing similar to GE locomotives and the placement of dynamic brakes at the rear of the locomotive. Key spotting difference between the SD80MAC and SD90MAC include: no external rear sandbox on the 90MAC, more…

EMD 16-645F3B LATE EXH T Ed2 N XL L M4

The GP50 was produced in response to increasingly tough competition from GE Transportation Systems, whose Dash 7 line was proving quite successful with railroads. While EMD's SD40-2 was a reliable and trusted product, GE's line included locomotives up to 3,600 hp (2,685 kW) with more modern technology, as well as very competitive finance and maintenance deals. EMD responded throughout the SD50 program by offering discounts on large orders.

GM-EMD had previously produced 3,600 hp (2,685 kW) more…

EMD 8-567C NT N XL L M4

The EMD 567 family of Prime Mover was one of the most widely used in the world! From F-Units to Geeps this popular power house can still be found in many locomotives riding the rails today. Our EMD 8cyl version of the 567 would be appropriate for the following locomotives:

SW8, SW900, G8, GA8, GL8, JL8, And others.....

Recorded from a EMD SW8

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

Goodwin/ALCO 12-244 N XL L M4

In October 1956 the NSWGR took delivery of 4301, the first unit of an order for six locomotives to be built by A Goninan and Co at their Broadmeadow plant in suburban Newcastle. In June 1957 the last of the class, 4306, entered service. They were fitted with an Alco 244 engine and were rated at 1600hp (1193kW) for traction.

While recorded from a 43 Class this 12cyl 244 prime mover sound file would also work in the following locomotives.

RS-2, RSC-2, RS-3, RSC-3, RS-10, RSC-2, RSC-3, RSD-4, 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…

GE 12-7FDL12F17 N XL L M4

The GE B23-7 diesel locomotive was first offered in late 1977. Featuring a smaller 12 cylinder version of the FDL engine, it is the successor to GE's U23B produced from early 1968 to mid 1977, but at 62 ' 2" long, the B23-7 is exactly 2' 0" longer than the firms U23B. The B23-7 competed with the very successful EMD GP38-2. General Electric also produced a variant, the BQ23-7, for the Seaboard Coast Line. A total of 537 B23-7's were built for 9 U.S. customers and 2 Mexican customers.

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…

EMD 16-567D1 2EXH NT N XL L M4

The 567 prime mover is a line of medium-speed diesel engines manufactured by GM Electro-Motive Division. They were used in many EMD locomotives from 1938-1966 when it was replaced by the EMD 645. The 567 proved to be exceptionally successful in passenger, switching, freight, marine and stationary services. The 16 cylinder 567D1 variation could be found in the following locomotives:

FL9, GP18, GP28, SD18, SD28

Recorded from a EMD SD18

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…
