Miniature Servo (SG90)
Subminiature 9g servo.  These have plenty of power for hinged point turnouts and solid rail point turnouts. If the point rails are hinged then the rail size is not an issue - it has been used up to G scale, otherwise code 100 is max for non-hinged points . Size 1.25" wide (including mounting tabs) x 0.5" deep x 1.125" tall.  Servo lead about 7".  The label on the servo and the lead colors may vary between batches.  Works with all of our boards. Every servo is tested before shipping.
