Great Northern & Great Eastern Joint Railway (GER & GNR)
Explanation of column content is here.
Mileages seem to have been primarily from Huntingdon to Black Carr via March as shown in the GNR Gradient Book.
Milepost Mileages. 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, therefore, mainly from 1897.
