43066 & 43073, EM 17.45 London St. Pancras-Derby (1D90, 2L) & 222006, EM 17.57 London St. Pancras-Sheffield (1F60, 2L), Harrowden Junction
Signallers at control dealing with a problem at Harrowden Junction.
As the HST formed of 43066 and 43073 was due to stop at kettering they have put it on the down slow. This to allow the non-stop Meridian formed by 222006 'The Carbon Cutter' to pass it and head on fast to Leicester. Had the recently installed relief line not been available, this move would not have been possible until virtually in Kettering station so it saved the day as both trains arrived within a few minutes of their intended arrival times.
