The MP5's are a small switch motor with a planetary transmission.
They are smaller than a tortoise and also have a removable wiring plug too.
The sliding transmission is also adjustable:
They are small enough that even with back to back turnouts in the yard ladder, they can be positioned almost side by side.
The operation is purely horizontal in motion for a turnout, and positive enough that I didn't have to remove the centre over spring from the Peco - Code 100 turnouts.
I have all of mine running off a Digitrax DS64 via fascia mounted push buttons, and through JMRI via PanelPro.
