Casting retaining walls - plaster or resin?
I'm going to be trying out casting for the first time, I need 4-5 linear feet of HO retaining wall/bridge abutments for my latest project layout. Making the molds from RTV, but in doing lots of reading it looks like I could go with either plaster or resin for the actual castings.
Bachmann 4-6-0 Running Slowly
Hi all!
I recently purchased a used Bachmann spectrum 4-6-0 that came with a factory tsunami sound decoder. It runs, but very slowly even at full throttle on my DCC system. I've tried resetting the decoder and that did not fix anything.
Does anyone have any input? I am really hoping that I did not buy a lemon.

Ditch light timeline
We got some excellent information in the rail car storage thread so here's scouting for more insight this time on ditch lights.
I can find that they became mandatory in the US as of 31 December 1997, and that there was much earlier use of some kind of ditch lights in the Canadian mountain west by CP and CN; but I did not find any sort of conversion timeline by railroad.

1992 Walthers SW1 motor info
Hi all,
I have a friend that wants me to install a sound decoder in a 1992 Walthers SW1.
I am trying to find out if anybody has done this?
My real concern is finding out if the motor is wired similar to the old Athearn blue box locomotives that have it so you need to isolate the motor like Athearn.
Thanks,
Barry

Driving a 130' diamond scale HO turntable with an arduino and a stepper motor
A few years ago I purchased a partially completed 130' Diamond Scale turntable with the intention of putting in the Bear Creek yard engine facility on my BC&SJ railroad.
Finally, I'm in the process of installing it. The plan is to drive it with a stepper motor and an Arduino.
Sounds simple? Well not so much actually.
Due to my being lucky I have a good friend (and layout collaborator) who can make adaptor fittings to go between stepper motors and the 3/16" worm gear driveshaft for the turntable.

Adding doors to HO GP9
I'm currently constructing a scaled-down version of Union Pacific's diesel service facility opened in Salt Lake City in 1955. The interior will be detailed and include an EMD GP9 being serviced (using a "blue box" dummy unit, Walthers 567 prime mover, and Cannon Company doors). My hope is to carefully cut away the existing doors on one side of the shell then install the Cannon Company doors in their open positions so the prime mover is visible.

Rubber Band Drives
I've been doing a bit of research on alternative motor-axle drive systems to utilize on a 'disguised pusher' to help power up our steam engines that have been trying mightily to do it all on individual selfs.
A few days ago I ran across a few references, including this very convincing video,..
Car Storage
I've seen some cuts of cars parked along short line railroad sidings and even main lines for weeks or months without being moved, and I'm assuming (yeah) that these cars are being stored for a fee. None have reporting marks for the road they are stored on. I've also seen some that were there for weeks and then one day they were gone.
Weathering some Rapido GP20 tank cars
Rapido Model Trains recently released a nicely rendered model of the Procor GP20 20,000 gallon general purpose tank car. These were ubiquitous in my modelling era and locale so I need a bunch of them. I decided to try my hand at weathering them and they turned out pretty nicely. More here:
