It was a third class experience. There is no schedule given on your website. When I boarded the bus, the conductor told me that it take a longer route that usual and will reach Dharamsala at 7.30 pm. I had to get of the bus on the way at Ghaghas, and wait for another bus to Dharamsala. Between Ghaghas and Dharamsala I had to change three buses.
Please note that this is very troublesome for the passenger, if you do not provide the correct information. Do your home work first and then make your sale.
