HO Bachmann E-Z Track

Does anyone here have any experience with American HO scale Bachmann E-Z Track?

We go around to numerous exhibitions around the country normally demonstrating the UKTrainSim train simulation stuff - however we're adding a new facet to the stand talking about DCC this year for those shows that want it.

In order to demonstrate it we bring along a couple of loops of track (no room to carry a layout board!) - we've decided that the best way to do this is via the pluggable E-Z Track system since it provides a lot more form and structure (we used normal peco track the last time and it wasn't too great loosely laid on a bunch of uneven tables that we had been given).

We've got a couple of loops in various HO sets that we have anyway, however we'd like to demonstrate points as well - I see there are some points for E-Z Track and they come with motors, what I can't find anywhere is how these things are fitted?

Can someone with some experience give me an idea of how they are fitted? Are they fitted to the plastic or do they require a baseboard? Do they go under the baseboard and thus would need all the track on one to keep it level? Or do they actually fit under the track itself and essentially disappear flush to the bottom?

Any help most appreciated!

Matt.
