It's amazing the impact sound, smoke and lights has on steamers...
Martin that did those for me has been up to his eyes in recent years, I must poke him to see if he'll do some more, and capture some video on Amiens!
"The RPSI's ex-GNR(I) 4-4-0 NO. 85 "Merlin" was in steam on Thursday night, 5th December. This was for some test running, including testing the speedometer and the AWS. There was also a lot of posing around under the yard lights!" From Mike Beckett

(it was designed entirely to bank heavy trains up mountains!)

Got into the attic for an hour last night, so managed to lay the freight yard, some concrete on the per-way shed and decided to rip up the running shed, am thinking this will be a small DMU servicing area instead!
