I suspect that they are posting there because one or both of them have paid for "First Class" memberships there, and therefore have space available there to upload pictures to illustrate what they are doing.

I don't see a problem with that.  Anyone and everyone can go there and read their posts--no one is being excluded.

Hybrid drive is simply battery backup for a DCC loco.

For those not familiar with this usage of the word "backup",  it here refers to having a little bit of stored energy available to get the train past dirty spots on the track.

I believe that large capacitors are also sometimes used instead of batteries.

... as there are commercial models in F Scale Standard Gauge as well as Fn3!

That's something I haven't run across yet!  I did know that Iron Creek is making tie strips for F Scale standard gauge, but I didn't know there was anybody making commercial models for that gauge.  Could you give us a pointer or two to their web sites?
