153-C Contactor Solution ?

[traindaddy1]

Well, here we go again!  (Attempted to post a  picture but my "@#$%$#&" computer is not cooperating)

Have several road crossings spanning three 027 tubular tracks.  When a train approaches from either direction on any of the three tracks, the crossing guards on both sides of the road come down.

Here's the problem: The crossing guards don't stay down long enough until the particular train completes its passing. They reset to the upright position. We are constantly adjusting and re-adjusting the contactors.

Question: To the best of your knowledge, is there a real (cost-effective) solution?

As always, many thanks.

Yes.  Insulate an outside rail along the length of track where you want the crossing gate to operate.  Connect one terminal of the crossing gate to that insulated "control rail".  Connect the other crossing-gate terminal to the voltage supply that you want to use to operate the gate.  This supply should have its common connected to the outside rails of the track generally.  You can use the track voltage or a fixed accessory voltage.

Bob:  

Thanks, so much for the reply.

I'll give it a try, that is, as soon as my hands warm up. Been a "bit" cool here in Orlando.

I always learn something about the hobby from you. Thanks, again.

Lionel has a good reference HERE for setting up insulated track sections.

For realistic operating gates or banjo signals, expand on the simple single insulated track method .  If room permits, insulate one outer rail on 4 or 6  adjoining sections  ( or an entire 36" section ) with the road crossing positioned mid way along the sections.  Wire this as you would the single section diagram.   In this way the gates drop before the engine reaches the crossing and raise well after the last car crosses.  Just like the real thing.

A three track crossing?  Multiply by 3.

The best idea I have heard for making insulators for the modified sections of track is to use gasket paper which is available at a car parts store.  Vinyl tape does not work very well.

Rob; Bruce; Servoguy:   Appreciate it. Thanks.

Or the fish paper center rail insulators from scrap track sections.
