It is a pity the 0927 doesn’t run, there is less of a need for an early morning balancing service from London. But it would fill in a gap at all stations along the line (Newark and Peterborough impacted more then Grantham)
The unit would I assume form the 1206 London - Lincoln - currently formed using the ex-Middlesbrough service. The 0806 missing Stevenage as a stop is always interesting, I assume it has a conflict somewhere.
Going North things are not as bad with Departures to Lincoln 0806,1006, 1206, 1406, 1606 and 1906. I think a balance working would be better at 2106 rather than 0606. But the northbound service is better spread out anyway. Combined with the York service is is pretty much hourly standard pattern between 0706 and 1606 (with the 0806 exception)
