I just received several images of scale correct rail by TT Filigran from Germany - thank you Helmut! This is a #6 turnout:

Non-insulated frog? My electrical skills would not be able to handle that! :crazy:

That looks pretty much like a standard model railroad switch except for the doubled ties in a few spots and those thin guard rails. The metal frog allows a powered frog for better running reliability, a switch machine or hand throw with powering provision takes care of the electrical problem....dave

Definitely, on the permanent layout, with a switch machine, a couple of insulating joiners and the power connector it should all work out fine. I am just sooo scared of the short circuits! :crazy:
On another note, can someone read abck and see who should get a prize for thread derailment on this one? Or, are we still on topic? :think:

I'll take that prize. I guess. The topic is wheels but since they are to some degree dictated by the rail, I think we're still "topicing".

Hi, Could you tell me more about replacing the PVM /Tillig GP9 power kit wheels with smaller flanged wheels? All my cars have HP size flanges and I'd like to use the same size flanges on my locos so the track frogs and guard rails flangeways can be the correct width and depth size for the cars.
What kind of operation is involved in removing and replacing the TIllig wheels with the NWSL wheels? Do the P87 profile wheels run well with HP size flanged wheels or do you use strictly P87 profile wheels on all your cars too? Does NWSL make a wheel that would match the standard HP size wheels better ? Anyone who has solved this wheel/track standards problem please offer suggestions? Thanks Dave Branum

A little more searching and i found the right topic this time. Here's an updated draft of a 36" scale wheel set on a 1.5mm diameter, 18.5mm long axle.

nice. is this a product that might see light of day or just a bit of CAD doodling?

i think given the cost of NWSL wheels, some other source of supply would be handy.

not sure how lucrative a business it would be though.

Just a doodle for now. I'm trying to stay focused on this GP35 locomotive. I was looking at drawing up a 100T roller-bearing truck to go with. Man, TT is a virtually untapped market with boat loads of potential!
