The special was hauled by 35028 Clan Line, a Merchant Navy class Pacific. She's a big locomotive, powerful enough to haul a full rake of pullman coaches - and a freewheeling diesel locomotive (needed for the section from Didcot to Oxford which isn't rated for mainline steam) - and makes an impressive site as she pulls up the climb from Wandsworth Town, on the run out of London towards Reading and the West.
Clan Line passes a South West Train electric, two generations of Southern rail...
Full steam ahead through the Putney cutting, with a long rake of pullmans behind.
Reflecting the bridges in the shine of a polished boiler, Clan Line heads into the Putney straight. Spot the diesel trailer car!
And away it goes, shrouded in steam and smoke through the three Putney bridges.
Into the West.
Well, at least into the Great Western!
