Forgive me, but it's been nearly 15 or more years since I've been involved in HO scale. Due to several changes that have taken place in my life in recent years, I'm considering switching back to HO from my current S scale. I am so totally NOT up to speed on what to expect in HO nowadays, hence these questions. Here we go with round 2: * Is there a ready fix for the Life Like P2k split axle gear issue? All of my stored P2K have split axle gears. * How do the newer Athearn units run? In particular, the Genesis F-units and their new GP9. Do they make a GP7 also? * How does the "new" Altas stuff work, in particular, the new S-2 w/DCC and sound. Anyone have one? How does it run, how does it sound? * How does the Atlas code 83 track system perform? Mainly the Custom Line and Super Track switches. What's the difference between the two? * Is there a good HO forum to participate in? One that has a generally friendly atmosphere and is laid back, yet still knowledgeable and experienced in today's HO? I have much to relearn. Okay... all for this post. I will say that at this stage, the indicators are pointing toward the very real possibility there will be an HO version of my West Bottoms/KC Lines theme in this small space I have to work with instead of an S scale version.
