Jasmine is a purple tender engine from the Pennsylvania Railroad.
Jasmine is based on a Pennsylvania Railroad K4s Class Pacific. Two K4s are preserved, 1361 and 3750, and are recognised as the State Steam Locomotives of Pennsylvania.
In real life, Jasmine would be too large for the British loading gauge. However, she has been re-scaled to avoid technical issues. Jasmine is only partly modified to work on Sodor. Her running plate has been altered, she is missing a headlamp, and she has buffers on her tender and screwlink couplings, yet she retains her cowcatcher.
Jasmine is painted purple with green lining. She has a green cowcatcher and piston rods. She also has "PENNSYLVANIA" written on her tender in green.
