I just wanted to assure anyone thinking of buying the Peco PL-11 point motors, despite what it says on the Hattons webpage:

"N gauge points will need to be raised by approx 2mm for the drivebar to engage correctly with the tiebar."

I can confirm that I have fixed the point motors on my 'N' gauge layout, minus the mounting plate or any other accerories and with absolutely no modifications - and they work great. No detriment to the folks at Hattons, just my experience today.
