Update February 2015: NJP to Darjeeling Toy Train Service has remained out of service since June 2010. A section of the track was badly damaged before Kurseong near Pagla Jhora due to landslides. So there has been no toy train from NJP/ Siliguri to Darjeeling since then. But now the track repair is almost complete and the service is expected to resume soon. Some trial runs have already been made.
