PL-26
One relay will not do the job. It would leave power connected all the time to your points motors, not good -- points motors,burn up.
PL-26 is a momentary single pole, double throw with center off switch. This equals two relays, one to open points, one to close points.
For many turnouts or points as you call them, you could have one direction relay and then one relay for each turnout/point so that you can power it for a short time.
