When I am updating train pic of a memu or a Demu ..Some TLMs are confirming it.. while some are giving void... Similarly ... Regarding the CC of memu and Demu.. many memu and Demu trains TT in iri are showing CC.. BT when I'm updating it why m I getting void???
Anybody with a view.. what is the rule regarding train pic and CC of memu / Demu.. Whether it should be updated or not..
