Here’s my idea:

Place IR-LEDs in the layout’s lighting valence – driven, perhaps,
by a picaxe at 38kHz (the freq. used by tv remotes). This will
flood the layout with IR – but should be easy to differentiate
from background light since it’s not only IR but at 38kHz pulses.

Hello there I was wonder what size wheels do I need for the old walthers kits that mostly oil tankers. Do I use 33" or 36" wheels?

I was wondering what is now going to happen to steam trips after the accident that killed a woman standing to close to the tracks. Will this be the end of all trains rides because of insurance cost getting out of reach, like it is already, or will this be a wakeup call to make people stand away from the track, or now be run off because the railroads won't want anyone near the rails. Maybe fences will be put up to keep people away from the tracks, or police running you off or in worst case taking you to jail.

I run my actual layout with NCE, but I built this DCC++ command station for an upcoming demo at the local NMRA division meeting.  I thought running the ProtoThrottle through the $50 DCC++ command station would be a fun way to wrap up the demo.

However, I'll keep the PT under wraps until the end of the presentation, or it will likely be the center of attention.

Here's a one minute video.
