The patio end of the line has been expanded following the arrival of some cheap faller play train points, with some slight modification these linked to the mamod track exceptionally well as the height from the bottom of the sleeper to the top of the rail is identical.
Unmodified track joiner..
Modified....

The joiner needs to be shortened, I left about 1mm of the linking plastic to retain a little strength. The track is too tall for the mamod joiner, fortunately there is a mould marking towards the bottom of the track, cutting along this and removing the bottom of the track this way makes it link up with the mamod track perfectly.
For some sections I modified broken pieces of mamod track (see my post in the General section about how it explodes!)
Now I have this on the patio...
However it turns out that the paving slabs have a very uneven surface with variations as high as 5mm so I'm waiting on some fine gravel to ballast it all before running anything other than a lightly pushed test truck.
