Jessie is a 16" 0-6-0ST (identical to our Arthur). However, every time she has visited Quainton she has been masquerading as Thomas™ with side tanks fitted. Jessie is usually based at the Llangollen Railway in Wales. Jessie has been at Quainton for the Days Out With Thomas™ events in July 2016, Sept 2016, Christmas 2016, Easter 2017, July 2017, Sept 2017, 4 days of Christmas 2017, Easter 2018 and Christmas 2018.

After Christmas 2018 the owner intends to put her back to original condition as a saddle tank so she will not be seen as Thomas after 2018. This has been completed, and now Jessie has reverted to a saddle tank configuration, in a black livery with rear cab wasp strips.
