An idea/thought for Menards

Would be a nice addition.  I don't know how easy it would be to make it somewhat scale.  Lionel had the one inspection vehicle that was scale or close to it but everything else was in the 1:32 range.  WBB vehicles are also on the large side.

I'd love to see a scale (1/43) 50's F-100 with rail wheels fitted on it instead of regular road wheels. But gauged for o gauge track, the greenlight DeLorean with the train wheels is off by (I think) over a centimeter. Doesn't even have to be motorized, just able to roll on a layout.

Like the wheels on this Caddy: 

And actually, a Cadillac like this would make a really great looking inspection car. 

I would love them.... powered is not needed, unless they wanted to make a headlight/flashing beacon 

Sourdough chimin' in,   I think all those ideas sound great.  I especially like the idea of a slow constant speed motor like MG mentioned.  Might be swell for Keith's Cadillac too.  Menards would be just the right guys to do it too.  I mean if they detailed 'em the way they've done on their other pieces they'd be a hit.
