I guess MTC-LJN has because the journey time is higher and some pax might wish to sleep instead as well. Though honestly, that trains sees a lot of crowd in the 2S coaches and IR would do well to add UR/2S sitting instead/as well.
Some other ICEs also have 2A like GKP ICE[via Barhni] and LJN-PPTA Express [both have RSA hence]. Agra ICE and Lucknow - Varanasi also have a AC 3 Tier coach. Though I personally think 2A is overkill, especially on short journeys.
