Last week I was in Mumbai for 4 days. While travelling by EMU 12951/52 Rajdhani and 12953/54 AK Rajdhani used to cross me each time UP & DN directions. I saw JP Duronto and INDB Durontos standing on the Staballing lines. But I noticed that all these trains were running with mismatched livery. Rajdhanis were running with 2-3 coaches of Duronto livery each time. On the other hand Durontos were running, suprisingly, with more (i.e. 6-7) coaches of Rajdhani livery. Then I could not understand the logic of WR of running trains with such mismatching.
