1. Solid cowcatcher and reflective paint : Not so necessary. Bhopal Shatabdi runs at 150 with a normal WAP5 which may or may not have solid cowcatchers and reflective paint is absent.
2. TPWS : This needs to be transferred to another WAP5 before it's attached to Gatimaan. I think GZB should equip all WAP5 locos with TPWS.
