Algodoo

The GE U18C diesel-electric locomotive was introduced by GE Transportation Systems as an export model road switcher. It was powered by the 8-cylinder FDL-8T engine. This locomotive is used worldwide with many variations and modifications. Different engines may be used, e.g. 7FDL8 and 7FDL12. Like the other members of the Universal series, it is compatible with all track gauges.
