Tom M, I have to say I admire your creativity, watching your other White Pass threads and now this one.
While there's an aspect of the hobby moving towards more realism, that accuracy and durability don't often go together. The easily broken switch lever on the FasTrack turnouts is a good example of that, and in my thinking, durability with maybe less realism would have been better. As you indicated to with your mention seeking interest for a simple knob to control these manual switches.
FasTrack is hardly cheap as compared to tubular, and since FasTrack is now the Lionel standard for starter sets, one would hope the manual switches would be a little more durable, as there is a chance that young hands will be operating them.
The MPC era 027 switches with their large housing box is not the most realistic design, but on the manual switches, it is certainly a durable operation. And I haven't had the problems that others have spoken of with the 027 switch tracks.
On mine, I drill a small hole in the level on those manual 027 MPC era switches, and then run nylon fish line to the front of the layout. So I avoid the headaches by design of the electric Lionel 027 switches, and yet get benefits of an electric switch.
In a hobby where the participants expect more and more from the "manufacturers" in this small niche (AND diverse) market, it's nice to read your threads where you are making things yourself. I personally don't have much hope for seeing any new 027-ish diesel engines, so I've taken to kitbashing and making them myself. Just as with my many repainting projects. Just because I'm an 027 guy doesn't mean I don't like current modern road names. And fortunately, many of the larger hearld HO decal sets work out just fine with the smaller 027 types of rolling stock and engines.
Nice idea and thanks for sharing it.
