From January, 2014 you can book retiring room online simply by using your ticket PNR.

Previously you'd need to go to Railway station.

जनवरी, 2014 से रेलवेज के प्रतीक्षालय कमरे/डारमेट्री या रुकने के कमरे अब आप ऑनलाइन घर बैठे ही बुक कर सकते हैं. आपको इस साईट: http://www.irctctourism.com/cgi-bin/rr.dll/irctc/services/rrhome.do पर जाने की जरुरत है.

Steps

1. Go to http://www.irctctourism.com/cgi-bin/rr.dll/irctc/services/rrhome.do

   

2. Enter your valid PNR in which you might have already travelled a few days back. Press "Search PNR".
3. You're taken to another screen, Click on"Book on Source" or "Book on Destination". If retiring room facility is unavailable then you'll be prompted.
