Jasiri is a tender engine who appears in the Spin Off Series of Emily ! Basis Jasiri is based on the L&YR Class 28, a clas of 0-6-0 mixed-traffic Tender Locomotive designed by George Hughes for the Lancashire & Yorkshire Railway and build by Horwich Works between 1909 and 1912. It was rebuild of Aspinall's Class 27, with the addition of a Belpiare Firebox, a Schmidt/ "Twinplug" Superheater and the extension of the Footplate and front Sandboxes. Jasiri is an experimental member of the Class 28s; he is fitted with a front Pony Truck ( thus making her a 2-6-0 instead of an 0-6-0), 5'6" driving Wheels instead of the 5'1" ones and a Fowler Tender. His front Sandboxes also appear to be mounted underneath his Footplate rather than joined to his leading Splashers. James and one of The Red Engines shares the same Base.
