Onibury signal box (BR, 1977)
Onibury signal box (BR, 1977) 
 Having criticised Railtrack's attempt at building a new box in the 2000 at Craven Arms, BR's attempt is pretty awful too! It is a BR (WR) Type 37 box that was constructed in 1977. Despite some searching, I have been unable to find a reason why this was constructed and if it replaced another signal box, can anybody shed any light? As an aside, my notes from my 1981 visit state that at Onibury there was a 'new signal box'; it would have been just four years old then!
