Yass

Yass is an Australian tank engine that works for Tri-ang Railways on Nerland. He is known for taking more coal that he really needs and one of the most reliable Australian tank engines on the railway despite his age.

Biography
Yass was built by Beyer Peacock & Co. sometime between 1877 and 1882 as a NSWGR 79 class 4-4-0 until rebuilt between 1896 and 1902 into a CC class 4-4-2T for suburban duties. In 1924, he was renumbered to '1313' from '172' and was withdrawn in the 1960s after the Yass branch line services. He was bought by TR in 1971 due to the need for an extra locomotive to assist in Matilda's suburban duties following the stepped up timetable.

In 1978, Yass was given charge of his own branch line that TR originally closed to passengers during the First World War and assisted in reinstating its passenger services to the local communities and industries, which he operates as a "tram".

Livery
Yass is painted in NSWGR Lined Black with yellow and white numbers.

Basis
Yass is based off the real locomotive of the same number. 20 were converted from C class 4-4-0s to CC class 4-4-2Ts following the lack of suburban tanks and the number of C class locomotives made redundant, with these conversions carried out by Eveleigh Works between 1896 and 1902. In 1924, they became classified as '13 class' and numbered from 1301 to 1320. The class was normally reallocated to different parts of the New South Wales Government Railways (NSWGR) system when they were replaced by S/30 class 4-6-4Ts in those areas until allocated to working the Ballina branch, Picton-Mittagong Loop, the "Yass Tram" and North Coast school trains. The class was withdrawn from service in the 1960s and three have been preserved.

Trivia
Yass' service is known as a "tram" in NSW, due to it having only the driver in the cab and the conductor in the carriage.

Yass was named after the town in NSW, Australia, where a few 13s worked the "Yass Tram."

Yass' behaviour was inspired by one of the drivers on the "Yass Tram."

Yass features the original bunker design.

Due to this origins are a Beyer Peacock engine, Yass has a Lancashire accent instead of an Australian accent.
