When I worked in the booking office there was a small number of people who came in to pay the rent on their railway-owned houses. Claughton Road and Euston Road were two of the street names I remember, suggesting that they were built by the L.N.W.R., but they were of a design more suited to management staff.
Looking out of the window on the W.C.M.L. you will see the distinctive L.N.W.R. design of terraced block of, usually, up to 4 houses. They are identifiable particularly by the courses of blue brick along both storeys, and are usually near to a bridge and quite remote. An example near here is now called 'Fog Cottages'; although they mainly accommodated P.W. workers this is presumably a reference to the widespread use of p.w. men also to carry out fog signalling, fog being more frequent than nowadays.
Even up to the end of the last century, I know of a family in. a village who lived in a house tied to the father's employment as a carpenter. Tied cottages on farms were still common when I had more involvement with farms.
