Superb shots there, and so lucky to have it slow down then open up. As for 3 napiers yep it would sound nice however i'm not so sure the traction motors would hold it though. You can melt em with just 2 !
exellent listen to the 2 engines growling away at the min this is the best train with a main line cert running forget about those rubbish 43s replace them all with a new fleet of super deltic with 3 napier engines keep on growling rsg
