On 18th Of April 2010 I had taken the Whiteliner Bus service from Siliguri to Kolkata. The bus was full, it run for 4 hours and just after Ranigung it stopped working and we had to stop at a dhaba. One local mechanic told the engine had to be open and it was complete one day work. We were left with our luggage at the dhaba, with the defective bus. Everybody was angry.No other alternative arrangement was done by the Whiteliner Management.
I had to catch 2 bus, one till Malda and other from Malda to kolkata, so instead of 12 hrs of journey it took 19 hours. We had a total harassment. We came to know that the in Whiteliner bus service this often happens. On reaching kolkata the Whiteliner service gave us refund of Rs 400. that also after approaching them several times. The total price of the ticket was Rs 650.
I would advise you all not to take the Whiteliner Bus service. Instead take the Rocket bus service if you are not getting any transport from Siliguri to kolkata.
