Points (switch) problem.

Gentlemen; <br /> <br />I have fixed th problem to an extent, by doing all the things i mentioned previously and some of the things that contributed to the problem: <br /> <br />1) Fines in the bearing under the points movable part. <br />2) Fines in the MTS actuating point motor. <br />3) 1 Point motors throw out of adjustment and poorly lubricated. <br />4) Poorly lubticated points. <br /> <br />I actually removed both point motors from the points and got the points working so freely that they would actuate with a side to side lean of less than 45 Deg either way. <br /> <br />But the real problem i think is the residual magnetic inertia within the point motors and this is why i have said it is only fixed to an extent. The effort needed to move a point motor compared to the effort used to move the points themselves is very high and i am convinced that this type of application is not meant to be. <br /> <br />The points i am having the trouble with is S13 and S 15 A and B is nearby and as i never want to use MTS on S13 unless S 15 is in the bypass mode i am going to fit a supplementary switch to S15 which is STDP (single throw double pole). This will connect the MTS circuit to the single point motor when S15 is on bypass and the rail switch contacts when it is straight through. <br /> <br /> <br />Rgds Ian <br />
