While booking online Train/Air ticket after debiting the amount fm card,if power goes then what about amt.?

1st thing you should have a Power Backup or UPS
2nd utill the whole process is complted money does not get charged to your card . If Money is charged be rest assured you will get the tickets . and for more help there is always customer service.

If you just debited the amount and the power goes off, the airlinetrain booking site is still likely to get the amount. Simply enter the transaction no. (they give you this before you press the 'pay' button) as the power comes back, and they will give you your ticket. The amount once debited is already sent, and is their responsibility. If the failure in connection results in no ticket getting booked, go to the complaint site and they will send your money back in 4 days time.
