Two 3mm flicker-effect LEDs, one red,one orange, in the floor of the pit. Covered with a single layer of tissue then brushed with PVA to form a hard shell. I then covered it with sieved ash from the NYMR.
Total cost about 50p.
Great effect at a great price.

It did cross my mind. I made the assumption that a dirty old steam era pit probably wouldn’t have working lights - probably got that wrong. :D
This is steam days and as its an Ash pit not an inspection pit no illumination other than a possible yard light high up on a telegraph or similar post nearby is about all the illumination available. Even inside in an engine shed in steam days an inspection pit probably wouldn't have had any pit wall lights. The fitters or loco crew would have used oil lamps.

Does that mean I was right? That’s twice this year - better have a lie down. :lol:

Thanks for the comments, it was an experiment that seemed to give the right result.

As always with work to retrofit anything on the layout some collateral damage is inevitable so today has seen some repairs to the various lighting circuits under the board - not easy when the power supplies come from the adjacent board which is in the other shed!

Ultimately I only had one yard lamp damaged beyond repair - not the end of the world but I must think of a satisfactory way to make things like that removable but functional.

With a bit of luck the engine shed board should go back on the main layout tomorrow so I can focus on getting the TT working correctly.

Can you guess what it is yet?

Yes. I made one of those but the end fell off.

A "plug-and-remove" yard lamp? R-

(p.s. wild guess based on post #165)

Jus checking who has been keeping up. :D

Correct, by the way. Or at least that’s the plan.
