Being that its a hobby one would think you would stay in G scale as you like building and yes you can build anything in HO. The only reason I switched year ago as no room for HO and as one gets older eye sight comes into play for the smaller scales and also handling of the. I go through stages of not operating my G scale as I did with the HO as I got bored and change direction for a while to take a break. I still love the G scale and now considering removing ground RR and now make it a table top out doors as I got a new interest being Live steam. So many new ideas for this new RR which will include having the RR wired also for DCC. This has raised my interest level to a new high and planning the new RR and compiling my material to start construction has got me motivated again. One must look at it as a hobby and enjoy the building as well as the running of the RR no matter what scale. Later RJD
