On Saturday evening (28th Jan) I saw the DISAB1 ballast suction unit formed of three wagons at the Met line bay platforms at Baker Street, and was noting down the wagon numbers but I couldn't get the third one.
I could identify CM955 and CM951 but am wondering what the last wagon is. According to this website the third wagon is JLE2 but when I looked on flickr JLE2 looks like a normal GP wagon.
Has JLE2 been rebuilt or can anybody identify the wagon?
The unidentified wagon had "2 Extension Hopper" written on the side.
I know the DISAB was having extra hopper capacity added to help with the Baker Street to Finchley Road concrete track replacement, so that would tally with the "2 Extension Hopper". The DISAB modules are clamped onto the solebar of the host vehicles, so JLE2, although being a GP wagon, could quite easily be converted into additional DISAB hopper capacity.
