Railway/Fitting Peco point motors

Peco point motors are widely used as they are relatively cheap (though Tortoise motors are now almost as cheap and if you source them in the USA actually cheaper). There are two common ways of mounting them: under the baseboard and through the baseboard. Both have pros and cons.

Through the baseboard
Advantages: Disadvantages:
 * Less fiddly
 * More dependable
 * Weakens the baseboard
 * Tangs visible

Under baseboard
Advantages: Disadvantages:
 * Less visually obtrusive
 * Easier to replace motors
 * Smaller hole in baseboard
 * Requires long pin motor and trimming
 * Fiddly to get right
 * Requires extra component (mounting plate)
