Old Brass/ME Turnouts


Robert Herrick
 

I've got enough track down at Espanola using Micro Enginerring Code 70 turnouts. I'm running a Balboa T-12 and C-19 and a Westside C-16 and all of them get stuck on the frog. The clearances are a little tight using the NMRA gauge and I've tried to clear them out with a file, but the problem persists. I wondered about the flange depth on this old brass, but the locomotives are fine elsewhere. Have you encountered this problem?

use a short section of hack saw blade.  just go down straight and slow.

Great idea! Thanks.

Have you checked the locos themselves?  Older brass is notorious for off gauge wheel sets, particularly but not limited to the tender and loco truck wheels, but occasionally drivers too. Mostly set too narrow by an NMRA gauge.

, so please excuse the typos.

Yes, I have, Mick. The flanged drivers are what get hung up on the frog. I checked and they are correctly gauged.

Then I'm afraid that the issue is your locos, not the turnouts.  I have many of those turnouts in my layout, and all my locos (50+ with old and new brass plus Blackstone and others) and 250 or so items of rolling stock run through them just fine.  Your older brass either has flanges that are too deep or too wide, if they are in gauge, and the NMRA gauge should tell you that, too.

The week may start M,T but it always ends up WTF!

Thing is, all the locos roll through the turnouts and on straight track just fine--it's only the frog where they hang up. Too deep flanges was my first guess, but others must have run Balboa and locos through ME turnouts. I've heard the old Japanese brass, ca 1950's and 1960's, have flanges too deep for code 70, but the Westside is a 1970's product. I've built a number of standard gauge turnouts using Fast Track jigs and tools, but I avoided buying the HOn3 jig because I only needed four turnouts for Espanola because at $129, the cost/benefit ratio did not support the jig. The ME frog appears to be cast. Perhaps Fast Tracks is the way to go after all?

If you feel your flanges are the problem, there is only two answers, make the flanges smaller or deepen the frog areas.

Yes. Problem solved. Used a Dremel to deepen the frog and everything works fine. Thanks for your responses, everyone.
