Haldwani and Kathgodam were two different townships in the past but now it has amalgamated in one unit. Kathgodam means a depot of wood. In the days gone by from Kumaon region timer was collected and stacked at this place and then transported away. Haldwani word was derived from Haldu tree (Haldina Codifolia) and Bani meaning a small forest. Up till recently Haldwani had huge amount of Haldu trees having yellow coloured wood. Meetre gauze railway line was built in 1892 by Rohilkhand and Kumaon Railways which was later taken over, by Oudh and Tirhut Railways. Recently all the railways were nationalized and it came under North Eastern Railways. The tracks have since been changed and are now having broad gauze line from May 1994.
