CTC Flat Wagon --- Another unique catch !!! This single truck Flat Wagon trailer car is usually gets towed by the FW trams or the Rail Scrubber trams and were used for carrying rails, ballasts, cements & other construction materials to various parts of the network across Kolkata. It is actually a base truck of century old SLC type tramcar. This very rare piece of marvel was spotted by Roy while it was parked inside Rajabazar shed on 16th November 2019.
