Not really much as pictures go, but I spent this week installing LED lighting into my Blue Comet and Alton Limited set passenger cars. What a difference; used Gunrunnerjohn's LED power supply modules along with some over-priced LEDs from MicroMark. At least there is now even/non-flickering warm white LED lighting that produces no heat to warp car roofing in the command environment.
The last photo shows my LTI MOPAC set observation with LED lighting installed. That set is now updated as well.
