I cant tell you anything about the coach body in the photograph but it may be something to do with the East Anglian Railway Museum which is located to the right of the signal cabin in the picture. Chappel & Wakes Colne apparantley is their HQ. There is an excellent view of the site on Google Earth. Hope this points you in the right direction to find more info.
