Photographed at Siding at Santipur NG Yard. These 2' 6" Narrow Gauge Passenger Coaches are bogie-less twin axled (four wheeled) vehicles. These Coaches use two leaf springs per axle. They have two doors each on either side. Some Coaches have two more doors on either side for the Guard’s Enclosure at any one end of the Coach. Santipur & Nabadwip Ghat, | 23 January 2003 |.
