you can catch ..rule is before 24hrs of arrival at amritsar.....IR website says
1. Whenever a through passenger detrains at a station en-route for catching a connecting train, it should not be treated as break journey provided such halt is for less than 24 hours. For example, the holder of a direct ticket from Pune to Jammu Tawi via Dadar travels from Pune to Bombay by any day train a day earlier in order to catch Bombay-Jammu Tawi Express next morning leaving Bombay at 6.25 hours shall not be treated as break journey.
