Is Graham Farish track compatible with Peco N gauge track?

In line with MOROP's NEM standards, Graham Farish track is completely compatible with Peco's, however, most modellers don't like to mix different manufacturers track.

It is not just Graham Farish's and Peco's N gauge track that modellers don't like to mix. Generally, it is not desirable in most modeller's eyes to mix any track, in any gauge, from any manufacturer. This has little to do with the compatibility of the track and more to do with the tiny differences in them aesthetically, from different sleeper spacing and moulded detail to variations in the colour of rails and finish to sleepers.

Don't let this put you off though, especially if you are planning to eventually ballast and weather your track because this will pretty much eliminate any slight differences in design between different manufacturer's tracks. If you have got an accumulation of tracks from different manufacturers then why not try giving a sample stretch the scenic treatment and see if you are happy with the end result. It could save you a lot of money in the long run!
