LTSR 3P 4-4-2T No 41943 leaving Kirkby tunnel in c1955. I think this is Annesley, with a Nottingham – Mansfield train exiting the North-West end of Kirkby Tunnel, viewed from Nottingham Road overbridge. Kirkby Tunnel was midway between Annesley Station 134m 65ch and Kirkby Station Junction 136m 55ch, so that would be the 135m 60ch (135¾) MP on left.
