On further improvement of BCNHL wagon doors RDSO come up with another design - Sliding door Pressed design with top mounted rollers on guide channel (see above photograph) which was developed in April-2010 and was provided on the wagons on trial basis. These wagons are primarily manufactured by Texmaco.
From amongst the designs tried in the field, the door design with top mounted rollers (300 Wagons) have performed with the least field problems. This door design with modifications to address all field issues has been standardised for new BCNHL wagons.
