If you travel by bus from Bangalore to Hyderabad (and this is probably the case with some other cities as well, but I have no first-hand experience), you get a choice of traveling in Volvo buses. The buses have AC, they don’t toss you around every time there’s a bump, and they’re reasonably comfortable. Except for the seats of course.
Most of the semi-sleepers have reclining seats. You can also move the arm-rests back. The problem is that the arm-rests don’t go as far as the seats, so you end up with the arm-rest poking you in the ribs. So, if you’re planning a cozy two-some with your significant other (or a hot stranger), don’t.
Then, there’s the leg-space, which is not so bad, unless you’re a bit tall. I am. The design problem there? Well, you have this iron rod that’s about two inches off the ground that gets in the way of your feet. If you take off your shoes, then the underside of your feet hurt when they have to rest against the iron rod or pipe or whatever it is.
Also, some bus drivers will stop and in the middle of the night (about 3 am I think), there’s this guy who comes into the bus saying, Jew-shh, jew-shh saar? (Juice, juice saar.) I am not a violent person, but I’ve experienced this a couple of times, and I’ve really wanted to do some serious physical damage to the guy. There’s something about losing sleep that makes you want to do things that you don’t normally do. Now I know why sleep-deprivation is used for torturing people.
Give me a train journey any day. Except that the tickets are not so easy to get as buses.
