This was the first such installation to be approved by the Board of Trade.

Great Northern & Great Eastern Joint Railway (GER, GNR)

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

Mileages seem to have been primarily from Huntingdon to Black Carr via March as shown in the GNR Gradient Book.

The GNR included an item in its weekly notice for 4 to 10 April 1897 headed "Remeaurement of GN & GE Joint Lines". This indicated that the lines had been remeasured and new mileposts were being put in place from zero at Huntingdon South Junction and running thence to Black Carr supeseding the old branch mileages in the area bounded by Huntingdon, St Ives, Needingworth, March, Whitemoor, Spalding, Pyewipe Junction, and Sykes Junction.

The existing posts between Spalding and Sincil Junction were being brought southwards from 8 to 12 chains.

The avoiding line at Sleaford would have mileposts from Sleaford South Junction.

The avoiding line at Lincoln would have mileages from Greetwell West Junction.

No Joint line mileages would be placed on the GER at St Ives or at Marsh or on the GNR at Spalding, Sleaford and Lincoln.

Mileages in the lists below date mainly from 1897 in consequence.
