HO-Scale Bachmann 2-8-0 with a Vanderbilt medium tender shown prior to installation.
To start off this install, we must first remove the two tender screws highlighted above.
With the screws removed, gently pull rearwards at the front of the tank, while carefully releasing the front of the coal bin. The shell should life straight up.
Take care to release the handrails as you lift off the shell so they don't break.
The following photos are of the completed installation, but with notes to guide the steps.
Using hot melt glue, secure the LED facing upwards into the original light mounting post as was the original 12v bulb.
In this installation, as the shell is tight and small, it was necessary to open the front mount hole on the motherboard very slightly to be sure to fit the tender roof mounting
post. Likewise, the motherboard needed to be cut as highlighted above in red at the rear for the same purpose. With this modification, the mount posts for the tender could
connect with the frame, securing the shell properly. In doing so though, LED pads for the rear and #1 do not function. As we only needed two light functions (front and rear),
we simply set those LEDs to remaining pads that were functional.
The completed installation.
To maximize the sound quality and volume, with a sealed shell such as this, it is necessary to port the coal bin with random holes.
We drilled small inconspicous holes at various angles to vent the sound out and minimize the visual presence of them.
In the finished installation, with the rough coal appearance itself, they are not noticeable.
You can now plug in your WOW121 decoder.Now you can close up the locomotive and reinstall the coupler assemblies.
Be sure to be mindful of wire routing and reassembly of the shell as to not damage or foul the installation.
Your Bachmann 2-8-0 with a Vanderbilt medium tender is now WOWSound equipped and ready to roll!
