Hodderfly Posted June 13 Share Posted June 13 I am building a 4ft by 1ft 00 gauge shunting layout. I intend to fit two right hand short radius insulfrog points. I am wondering if I need a CDU and will the points work ok without one. I am going to install either two surface mounted point motors or two seep motors on the points. I am looking for the most cost effective solution. Link to post Share on other sites More sharing options...
Barclay Posted June 13 Share Posted June 13 You could always just throw them by hand. On a small layout you would lose no convenience by doing this. Link to post Share on other sites More sharing options...
RMweb Gold Geep7 Posted June 13 RMweb Gold Share Posted June 13 (edited) I'd be tempted, on such a small layout, similar to throwing by hand, is to use the wire-in-tube method to switch the points. But if you are really wanting to use point motors, as long as you use the right power supply, you should be able to fire a single point motor without a CDU. However, using a CDU allows a couple of things. One, you can throw more than one point at once. Two, I don't know how to intend to actuate the motors, but, unless you are intending on using stud and prob, the CDU helps to prevent a point motor burnout should a switch fail. I appreciate the need to keep costs down. For example, the Gaugemaster CDU (other manufacturers are available) is now nearly £20. But, to be fair, unless one fails (very rarely), you'll be able to re-use it on any new layout you wish to build.

GrumpyPenguin Posted June 14 Share Posted June 14 Have a look at these (probably a better price from retailers) ; https://www.gaugemasterretail.com/train-tech-pms3-3-point-motor-switch-for-3-wire-point-motors.html 1 Link to post Share on other sites More sharing options...

melvin Posted June 14 Share Posted June 14 You could use Gaugemaster GMC-PM10D Point Motor, no need for a CDU. You can add a Manual Switch, add Indicator lamps if you wish. I use them easy to install. I have had no trouble either. Link to post Share on other sites More sharing options...
