Ahmmmm ... Its my primary OS
That's why I said its just to be experimented with. Home users can afford to use it. There is nothing large at stake here. Linux specially the free versions are not good enough to be used in such a large system without any sort of maintainance support

If reliability of windows questionable and a Xenix based OS is preferred, still a commercial enterprise version of Unix/Linux should be the choice. But they will cost a lot more than Windows.
Xenix OS -> Errr ... this is 2008
Sorry, I meant Posix, which is like a rule book of sorts for all *nix Operating Systems and clones. I don't know why I typed out Xenix. :ashamed: Maybe reference to Microsoft made me type it out absentmindedly.

Don't intend to start a flame, but at least the information posted
should be correct.
Yep I am saying that what ever OS they choose, it would need solid backing and maintenance help. Free versions of Linux or any other Posix variant do not cut it at all. Paid enterprise version with guaranteed instant support and maintenance is the way to go. Those big enterprises who run their systems on free Open Source framework also hire technology experts in house to do the tech support and maintenance and that is an even more costly solution than buying a pre-packaged enterprise version of Linux.
If you look form the pure cost perspective Total cost of ownership for Linux is a lot higher than windows. People who use Linux at their homes or in low stake situations that do not need a lot of maintenance or support do not realize that and think it can be deployed anywhere free of cost.
Linux definitely has its strong points, but its preferable in enterprise situations only when you can afford the cost and its a lot costlier than windows.

I am not sure as to why they chose Vista over XP in the first place? Isn't Vista sluggish on low end configs? All this is just to run a single railway reservation application does not make sense. There will be s/w costs and new h/w costs when the appln behaves sluggishly under Vista.
Poor choice I would say.
Its not just for reservation system that Indian Railways use computers. Its a whole system that needs to manage train times, arrival/departure scheduling, rail switching, Information sharing and synchronization. Any glitches in their system can results in problems ranging from as small as delays and non-availability of information to as large as accidents.
With the right support and maintenance deploying Windows is a lot better than deploying a free version of Linux or any other OS. Of course Linux is better when you have paid support or hired in house experts, but it would be a lot costlier too.
People are mistaken if they believe that they can just take a Ubuntu or Fedora core DVD, install it and setup the requisite servers and just start using it when you are talking about a huge organization like that.
