- BR carriage route availability code, often seen on heritage carriages.
- C1 0-8-0 Locomotive Class
- A LNWR 0-8-0 goods engine produced when class ‘A’ three-cylinder compounds were rebuilt into 2-cylinder simple expansion engines.
- Caledonian Railway (CR)
- Not part of LNWR, although the LNWR had running powers (which were not exercised) between Carlisle and Glasgow. The Caledonian and LNWR were of course allies and partners in the West Coast route.
- Calling On Signal
- Usually placed under a Stop Signal and, when operated, would indicate to a train driver to move his train carefully forward (past the main signal at danger) to either a predetermined location, or to the adjacent signal box from where he would await further instructions.
- Camden, London
- Camden is at the top of the bank out of Euston and was originally the site of engine houses for the stationary engines which worked the trains — a situation similar to that of Edge Hill. Again like Edge Hill, under the LNWR Camden became a considerable complex with a goods station (most through goods trains which did not go on to Broad Street terminated at Camden) and a locomotive shed for engines working the express trains to and from Euston.
- From the 1889 Century Dictionary of the English Language: A timber running along the tops of the upright pieces in the sides of the body of a railway-carriage and supporting the roof and the roof sticks.
- Capital Stock List
- Accountants have scheme called depreciation, where by an purchased item is written off over a number of years. While the stock item (locomotive, carriage or wagon etc) is being written off it resides on the Capital Stock List. When it has been written off, it is moved to the Duplicate list (for Locomotives) or Supplementary Stock List (for Carriages), and receives a different Running Number in the process.
- Caprotti Valve Gear
- Type of steam locomotive valve gear utilizing poppet type valves. Invented by the Italian engineer, Arturo Caprotti, it was claimed to improve engine efficiency. It was first tried in the UK on an LNWR Claughton Class locomotive in 1926. In practice it proved hard to maintain and was not as efficient as long-travel piston valves.
- Caprotti, Arturo (1881—1938)
- Italian locomotive engineer and designer of the ‘poppet’ type valve gear, claimed to improve engine efficiency. However, the design was hard to maintain, and was bettered by long-travel piston valves.
- Capstan Man
- In large goods warehouses, wagons and vans were normally moved not by locomotives but by capstans, using ropes working from a fixed engine and operated by a capstan man.
- A raised lip at the front of a chimney, intended to prevent down draughts when in motion and encourage smoke to rise above the line of sight for the locomotive crew. Sometimes they were made of plate steel bolted in place, others were an integral part of the chimney casting.
