BCNHL wagons have been fitted with doors which are different from conventional BCN doors. The first original design (type of doors seen in above photograph) was initiated in May-2008, but some problems/defects were observed by the Zonal railways in field during loading unloading. Existing design modified by improving securing of doors in June-2009. Modification was to eliminate gap between side wall and door at hinge, improving door securing & hence eliminating the possibility of door hitting & rain water seepage. But this also ultimately proved a failure.
