Look like the first train over the repaired Lamington Viaduct will be the " 16.04 Coatbridge to Daventry" with possible loco 66553. The video was filmed on Saturday February 13th. UPDATE. The Coatbridge to Daventry was cancelled so the first train that used the viaduct was the Caledonian Sleeper 1S25 Euston to IS FW AB. the 1M16 still went east coast to KX, and the 1M11 used the GSWR route.
