Some recent pictures of the progress on the relocating of Watersmeet Engine Terminal

The roughed in foam in the cut created by the raising of the Terminal subbase.

Since it nearly exist I use Peco Nscale code 55 track; Peco offer a great line of turnouts, crossing, and double slip.

All of them are handsome good trackwork and work quite well.

However after some years of use, they show some electrical problems, in fact electrical continuity trough the point; this is true on turnouts because of the hinged point which whith time take play and make false contacts.

I modify since years all of my Peco turnouts whith this method and they are become nearly electrical bullet proof.

I'm almost finished with this model!  It started life as a MTH 3 rail toy crane.  I converted it to 2 rail and added a S-Cab R/C system to control a Stanton drive.  The S-Cab radio is mated to a Tsunami sound decoder and powered by a LiPo battery.  The tender car is a modified Intermountain composite gondola detailed with all of the gear used by a crane.  I have a blow by blow blog going on the A&O Railroad website:

I know that HOn30 and HOn3 are two different scales and that they both run on 9mm track (Nscale).  My question is ... what is the difference between the two scales?  Is one bigger than the other?

Thanks for any info.
