 Initially WAG-7 had the body-shell similar to WAG-5 but later on all WAG-7 are/were fitted with crew safe shell like the WAP-4 since this provided more space and relatively safer during the impact on a head-on collision.WAG-7H have crew safe shell since beginning.Older WAG-7s have Tiger Face liveries (Red/Dark Blue on white) but newer WAG-7s by CLW have yellow stripe on blue livery.
