37198 has had a varied existence since it was withdrawn by EWS.
It was preserved in 2004 moved to the Wensleydale Railway where it was restored to working order and repainted BR blue - it worked its first passenger trains in preservation in May 2005. In 2006 it moved to the Dartmoor Railway, where it was often used on passenger workings. However, its owners (BRE Ltd) went bankrupt in November 2007 and 37198 (along with 37905) was sold for scrap and moved to EMR at Kingsbury.
Luckily 37198 was sold again to Network Rail and moved to Rothley on the GCR, where it was repainted in NR yellow, and had a number of repairs carried out. It is currently on long term loan to the GCR but is likely to return to Network Rail later this year.
