8. No Truck or Lorry is to be placed on the Line except for the conveyance of materials; and any Truck or Lorry so used is to be followed by a man carrying a Red Signal, at a distance of =400= yards at least. No Lorry is, under any circumstances, to be moved on the wrong Line. 9. No Truck or Lorry is to be used in a =fog=; and the wheels of Lorries must be constantly =locked= when not in use. 10. No Lorry is, under any circumstances, to be attached to the =end of a Train=. 11. Should special circumstances require the use of a Lorry in the Tunnels, or otherwise than in broad daylight, it must be followed by a man with a Red Light, and notice must be given by the Foreman to the Policeman at the entrance to the Tunnel of the time he expects the Lorry will be required in the Tunnel, that the Policeman may keep on the =Red Signal= during the whole time, and caution any Engineman entering in the Tunnel. 12. Every Overlooker is to have a =list= of the name and abode of every Foreman of his district, that, in case of accident, he may be enabled to summon them immediately to assist in any way that may be deemed necessary; and should any obstruction take place, caused by snow, frost, slips, or other sudden emergency, he is instantly to collect the required strength to overcome the obstacle. 13. The Plate-layers are to desist from work when a Train is within =400= yards, and the Foreman must order his men to move to the side of the road clear of both Lines, to secure the men from the risk of accident by Trains running in opposite directions. If working in a Tunnel, and Trains are approaching in both directions, the Plate-layers must lie down between the two lines of way, till the Trains have passed. 14. If a Passenger Train approach within =ten minutes= of a Coal or Ballast Train, the Plate-layers must give the Signal to proceed =slowly=. 15. In the event of any Engineman neglecting to comply with the Signal to stop, or to proceed cautiously, as the case may be, the Foreman of the Plate-layers is to =report= the circumstance, in order that proper notice may be taken of it. 16. Every Overlooker is responsible that all =loose timber=, =stones=, =rails=, =chairs=, or other materials, as well as the workmen’s tools, are removed from the road, and the Line kept clear of interruption of any kind. 17. The whole Line is to be =inspected= every morning before the arrival of the first =Up= and =Down= Train, and care must be taken that the Rails are in gauge, and the Keys driven home. 18. On learning that an =accident= has occurred, a Plate-layer is to proceed with all possible despatch to the next gang, from which a Plate-layer will in like manner run to the next more distant Plate-layer, till information of the accident has by this means reached the Station. 19. Having communicated the information, the Plate-layers are immediately to return to give their assistance.
