 The Scotch express had left Peterborough at 6.24, about 6 minutes late.It did not slacken speed for the bad weather; it passed through Holme at about 6.37, the signals all showing clear, and arrived at Wood Walton at 6.40.The signalman there had set his signal levers to put his signals to 'danger' to protect the shunting at Abbots Ripton, but had not left his levers to set detonators at the home signal, nor did he supplement his fixed signals by displaying a hand-lamp from the signal box.
