Steam Era's UB kit has been built according to their form in this era - removal of the autocoupling surrounds and replacement with louvres, original bogies addition of the original handrails, and less obvious changes - removing the later style of door handle and replacement with the original type, side bracing and removal of the supporting brackets for the four wheel chassis springs. Other changes last for the UB life - the corrugated roof appropriate to thsi wide door UB and the lamp irons fitted for their original passenger train capability.
