The British Rail Class 143 is a diesel multiple unit, part of the Pacer family of trains introduced between 1985 & 1986. They originally worked around North East England but were later transferred to Wales.[1] The coaches are based on an Alexander bus body mounted on a chassis from a freight or Goods truck.[source?] Twenty-five units were built, numbered 143001-025 but later re-numbered 143601 - 143625.
