43067 and 43062 5Z67 1230 Heaton- Doncaster.
Grand Central's High Speed Train (HST) power car 43067 can be seen leading Network Rail's New Measurement Train (NMT).
The reason for GC's power car making a rare appearance on the NMT. Was the need for Test Runs for 43067 after coming back off major repairs.

The train ran 2 return trips between Heaton Depot, Newcastle and Doncaster. The train can be seen on its first trip to Doncaster passing Browney, just south of Durham. Sunday 28th September 2008.
