Tickets with transfer slip for travelling in more than one route in a single day. One can witness pre-Independence transfer tickets as exhibits along with CTC Howrah division tickets. Actually trams used to glorify the streets of both Kolkata and Howrah - the twin cities not long far ago, until it was decided to limit the services within Kolkata to stop further weakening of the Howrah Bridge. In fact, the Shibpur (Howrah) tram depot is still an important bus stop.
