Me again...   How can I tell which trains need 4 foot turning radius and which ones are 8?  With my 90 degree angle walls I assume I will need a G train that will need a tight turning radius. 

Also with 80 foot track will I need a bigger power source?  What do you guys suggest? 

Thanks so much!

Going to bid on this track...

(Aristo-Craft 11097 Case 4.5' Brass Track European/Narrow Gauge Track! NEW!! #200682624122)

It is available on ebay.  I'm wondering if it will match up with G scale track that I would buy from the local store?

It says European/narrow gauge track... does that mean it is different than standard G scale track?  Thanks!

I have a young boy that LOVES trains...  I grew up with trains that my father had and have always wanted to do some kind of set up...  Here is what I'm aiming at doing.  I have a 30x10 room that I wish to run a train set around in a wall/ceiling mounted system.  A few questions:

1.  What size train would be best for this?
          a.  Going to need a ton of track, which would be most cost effective?
          b.  Do I need to worry about any electricity issues with that long of a track?
          c.  My first thought would be to go to a G scale for visual reasons.
          d.  Do smaller trains have cheaper track?

2.  Does track come in sizes bigger than 12"?
         a.  Can I buy it in 5' pieces?
         b.  What kind of track do I need?  Brass?

3.  What should I look out for.... be aware of...  prepare for.. with that large of a track?

4.  Do all G scale trains work on G scale tracks?


That is all I can think of for now, any help would be greatly appreciated!  Thanks!
