Minitrix offers a motor for left turnouts in N scale: 1/160th under reference 14934.
It is possible to install a motor for left turnouts on a right turnout by turning it upside down. The motor will then be upside down, taking up less space and allowing it to be concealed under ballast, for example.
The Minitrix 14935 and 14934 switch motors are suitable for all the switches in the range as well as for double junction crossings.
