# GE C30-7

The C30-7 is a 6-axle diesel-electric locomotive built by GE Transportation Systems between September 1976 and May 1986 as an updated U30C with a 16-cylinder 3,000 horsepower (2,200 kW) FDL-series diesel engine. 1,137 were built for North American railroads.
GE's successor to the C30-7 was the C36-7, early versions of which were quite similar to the C30-7.

## Variants
### C30-7A

A variant of the C30-7, 50 GE C30-7As were purchased by Conrail in mid-1984. Externally similar to the GE C30-7 model, six tall hood doors per side (in place of eight) showed it had a 12-cylinder (rather than 16-cylinder) prime mover. Both engines produced 3,000 horsepower (2,200 kW) but the C30-7A's smaller engine used less fuel. The C30-7A units were built between May and June 1984.
Chicago Freight Car Leasing Australia purchased twelve former Conrail C30-7A locomotives in 2001 and used their traction components in the rebuilding of 442 class locomotives as the GL class. These entered service in Australia from 2003.

## Use in Estonia

In 2003 19 C30-7As were rebuilt and exported to Estonia as C30-7Ais to be used by EVR (Eesti Raudtee) which at that time was privately owned. The locos were numbered as part of Class 1500 (1558–1576) and were second-hand from Conrail/CSX/NS (USA).
In 2018, Operail (formerly EVR Cargo) announced it had completed its first conversion of the series with #1564. International Railway Journal reported, "Only the frames and bogies of the original locomotive were retained and the C30-M features a new centrally-positioned driver’s cab and a 1.55MW Caterpillar 3512C HD diesel engine." The converted unit has a 1524mm track gauge and weighs 138 tonnes. Operail's redesign makes the units suitable for shunting and line haul. The redesigned units are planned for internal use and export sales.

## Preservation

* L&N 7067 is preserved and owned by the Kentucky Steam Heritage Corporation. This unit was previously painted for Marshall University and numbered 1837.
* Brazil's only surviving C30-7A, Rumo Logistca #7202, was restored in time for use on Rumo Logistica's annual Christmas on Rails train in December 2018. This locomotive is one of seven C30-7As built for Brazil.
