Almost every concept of this government on different new type coaches failed
1. Antodaya is totally flop concept, except few routes most are flop
2. Humsafar is also not so popular, except few routes most are flop
3. 3 Tier Economy coach not so popular as was expected due to poor design concept
4....
more... Tejas is also not that popular one ( not considering Tejas Rajdhanis as those were Rajdhani trains given Tejas livery coaches)
5. Now Vande Bharat is popular but the number of VB trains government have announced, after all routes starts i doubt it will be profitable in all routes ( Except routes where Shatabdi or Jan Shatabdi trains r already running now)
