Tortoise Replacement ???
Posted by gandydancer19 on Thursday, May 5, 2011 3:07 PM

Someone in our club mentioned that there was a new turnout machine out that looked like a Tortoise, but had a black case, and was less expensive.  They also said it was advertised in MR a month or so back.  I have looked back to February and couldn't find anything.

Anyone know anything about it?

I did find the Cobalt, which was in a dark blue housing and cost more than the Tortoise.

Elmer.

The above is my opinion, from an active and experienced Model Railroader in N scale and HO since 1961.

I don't recall anything other than the Cobalt being mentioned or advertised, but an RC servo can be used and is cheaper than a Tortoise.  Tam Valley Depot sells a controller that allows a servo to be used as a switch motor, and this has been mentioned several times on these forums.

thought I saw a tortoise... but think it was competition. Will check. Either in MR or Railroad News

 Cobalts are expensive, even more than a Tortoise.

WHat you are thing of is probably RC plane servos. But do yourself a favor and use them as intended, that MR article shows how to make a stall motor out of them, and they aren't meant to do that. Companies liek Tam Valley have the proper controllers, and you can buy suitable servos on eBay for about $2 each - so the servo witht he electronics to control it properly is still less than a Tortoise. FOr the same price as a Tortoise you cna get one that includes the servo, a fascia controller with pushbuttons and LEDs, and it is ALSO a DCC decoder. The non-DCC controllers cost even less.

And there's Micro-Mark's Switch Tender.

  The problem with the Micro-Mark 'Switch Tender' is that it draws a lot of current(60 ma, even with the supplied limiting resistor).  This is way to much for an in-line bi-color LED.  If you do not need DCC controlled turnouts, the Tam Valley 'Octopus' is a very good and low cost way to control servo motors.

I just threw in the Switch Tender as yet another way to control turnouts.  Yes, I agree that it's nice to have the bi-colour LED in series with the Tortoise and that's a great feature.  For me, it's not an issue as I have a separate circuit for my indicators.  As for the high current draw of the STs, yes that's a drawback.  However, I've found that with the power off to the motor, the points are held securely against the stock rail, IMO almost as solidly as a Peco turnout.  So, I use momentary toggle switches on my STs.  Maybe in HO, where the rails are heavier than my N scale rails, it wouldn't be as secure, I don't know.
