Signal Fact 40
In 1889 the Great Eastern Railway commissioned the first electro-pneumatic signalling installation at Granary Junction.
Rotary levers were used to operate the various functions.

This page should be regarded as “Work in Progress”. The webmaster will welcome additional information for this page.
In the list below the information is set out in tabular form, spread over four columns. The column entries are -
| RailRef | The Line Code used in RailRef system. |
| Line Detail | The principal locations included within the Line Code. They are arranged in 'down' direction order. Locations shown are primarily stations and junctions to allow easy cross check against published atlases. Signal box names appear in italics where these are 'intermediate' to stations or have been shown to facilitate links from other pages on this web site. The inclusion of a station or junction name does not imply that there was always a signal box of that same name! |
| SBR | The section reference used in the relevant Signal Box Register published by the Society. |
| ELR | The corresponding Engineer's Line Reference(s). This will be blank for railways that never came within British Railways terms of reference. It will also be blank where British Railways had no surviving responsibility for infrastructure at the time the ELR system came into use. |
Milepost mileages are taken from a series of civil engineering documents forming part of RAIL798 at the Public Record Office. These were compiled by the LNER and variously date from 1928 to 1940, and remained in use by BR. In these documents zero mileposts are at Bourne Station, Coke Ovens Junction, North Walsham, Saxby Junction, South Lynn Junction, and Wisbech Junction and run as shown against the line codes below.
As might be expected some of the lines originally had mileposts based on more historic zero points and these mileages, as shown on 19th century OS maps published in the mid 1880s, are mentioned within the line code notes. Where it has been possible to calculate these by cross reference to the LNER series the calculated mileages are shown in brackets.
What is not known as yet is the date(s) when the old mileages were changed to those visible in RAIL798. A plan deposited in 1898 in connection with doubling of the line at Langor Bridge clearly shows a milepost from South Lynn thus indicating that South Lynn Junction had replaced King's Lynn (GER) mileages by that date. As the South Lynn to Bawsey Sidings line only opened in 1885 this points to a possible date somewhere between then and 1898.

These are marked with whole mileages from Peterborough and half mileages from Sutton Bridge. Official M&GN documents from c1900 quote mileages from Wisbech Junction. Was the OS in the habit of dual mileaging or did the MR do this - I have seen similar in other Midland Railway areas and the MR originally operated this section. Sutton Bridge Junction - South Lynn previously datum Spalding. They are referred to as such in the notice published in the London Gazette for 15 November 1881 (page 5977) and MR still showed these in weekly notices issued in 1899. |

A GNR Gradient book shows Bourne Junction 0m00c to Spalding Junction 8m36c which seems to match the PRO evidence if zero is Bourne station rather than Bourne Junction. The same gradient book shows Spalding (Holbeach Line) Junction 0m00c to Sutton Bridge Goods 15m58c (shown in brackets - but calculated from the PRO mileages - hence the discrepancy) and this is supported by the 1889 OS maps evidence as being milepost mileages. The date of change is unknown. |

The 1885 OS map shows a 59mp from Kings Lynn at Potter Heigham station. Kings Lynn mileages over the Y&NN section may have been short lived - South Lynn to Bawsey Sidings opened in 1885. The 1886 1:10,560 OS map shows a 1 mile post from Beach Station north of Salisbury Road Crossing and the 1880s 1:2,500 maps between Felmington and Honing show some dual mileage figures from both King's Lynn and Yarmouth thus indicating that the Y&NN was initially miled from Yarmouth Beach station. |
