Sigrid of Arlesdale, also known as simply Sigrid, is a diesel engine who works on the Arlesdale Railway.
The Railway Series
Sigrid of Arlesdale was designed as a 2-C-2 Diesel/Hydraulic locomotive by Ivan Farrier and was built at Severn Lamb in Stratford, England in 1969. She was built with a Ford 4 cylinder engine, but after extensive trials under normal traffic conditions, it was found this did not give enough power. It was eventually replaced with a 6 cylinder Perkins engine, and performance has greatly improved. Sigrid is one of four diesel locomotives on the Arlesdale Railway and was named after the Sudrian heroine from the eleventh century who secured the defeat of the Norman Invasion in 1094.
Sigrid is always stabled for the night at Arlesdale ready for the service train which takes employees to their places of work first thing in the morning, and back home every evening. She spends the rest of the day at Arlesburgh in by no means inactive standby duty. Even the most reliable of steam engines sometimes fail, or as more often happens, extra passengers require the provision of a Relief train when no steam engine is available.
Sigrid of Arlesdale is painted in a two-tone blue livery: BR Diesel "Rail Blue" with a light blue band.
