[modeleng] Re: Track circuiting & Loctite

Hi John (and Barrie, Peter and Phil)

I'll certainly be interested in any resistance measurements anyone is able 
to take, to prove whether or not Loctite acts as an insulator.  I think that 
any steam loco should operate a track circuit, because there are plenty of 
paths across the engine, through the axleboxes and motion, and as Phil has 
pointed out, there is probably metal-to metal contact at the shoulders on 
the axle on other stock.  I'm still slightly sceptical though!

The reason for the query is that my club is thinking of installing track 
circuiting on our ground level circuit.  Our elevated track already has 
automatic signalling worked by treadles, these work fine in the open air but 
I'm not sure they will like being buried in ballast!

Regards
Ron
