The Kutch Gurjar Kshatriyas (KGK) contributions to the Indian railways were widespread from the late 1850s to the latest reorganization of the Indian Railways infrastructure in 2003–2006. The community also widely known as Mistris of Kutch (or Mistry) migrated from Kutch to perform the work and were involved in the laying down of railway tracks and construction of rail bridges in almost all railway routes of undivided British India.
The Mistris of Kutch or KGK are a small ethnic community numbering only 50,000 originating from their 19 villages in Kutch founded by them in the 11th century. The names of these villages are Anjar, Chandiya, Devaliya, Galpadar, Hajapar, Jambudi, Khambhra, Khedoi, Kukma, Kumbharia Lovariya, Madhapar, Meghpar, Nagalpar, Nagor, Ratnal, Reha, Sinugra and Vidi.
The community were master-craftsmen, builders and architects of most forts, temples and palaces of Princely State of Cutch. Their expertise in building forts earned them the name Mistri from Portuguese, which later became the name of their caste.
