   Carefull there : any kind of sparking (like can happen with a bad contact   
   between the loc and the rails) could cause quite a power spike on the   
   solid-state relais and destroy it.   I would suggest keeping the relais you   
   now have.

   Use Andys' suggestion*.  Just make sure the snubbing network is upto the   
   task.   
      
   * Take a look at the H- or T-bridges used for stepper motors.
