34028 and going Main Line

I've been told, by a usually reliable source, that D6515 Lt Jenny Lewis RN will haul 34028 Eddystone to Southall. I believe 34028 was due to be in steam today (Monday) for more running-in/snagging/mileage accumulation trips. I don't know if any runs have been made, with the railway's [3 or 4?] dual braked Mk1 coaches, to check the air pump is working satisfactorily but hope so.

Previously sidelined 'Black 5' 45212, with a hot tender axle box at Weymouth, was repaired at Riley & Son but has since failed again going north [for Jacobite workings?] and was last heard of being towed back to WCRC Carnforth. Eddystone's somewhat hurried change of plans is to fill this apparent lack of operational air-braked steam locos at WCRC's West London base.

After leaving 34028 to WCRC's team at Southall, D6515 returns home light engine: https://www.realtimetrains.co.uk/service...3/detailed
At the moment I cannot trace on RTT when Eddystone's loaded test train will run nor the route it will take. However. Southall to Didcot (turning on triangle of lines there) and return has been used before and there are current rumours of a night time run there fairly soon after it's safe arrival. We'll have to wait and see what happens I suppose.
SLL believe that, all being well, it has been pencilled in for the Swanage Belle on Wednesday 10th September! Here's hoping for a faultless tow to Southall and a faultless loaded test train workout.

Not heard anything about BR (ex-LU) BSK support coach 35011 recently so, presumably, that it still undergoing necessary conversion work at Herston prior to taking up it's new main line support coach role. Perhaps another D6515 trip to take it to Southall or will it be attached to the returning Swanage Belle if ready in time?
