As far as I can tell it's a question of potayto or potahto, depending on the year or circumstances.  I do have to admit that for a new guy looking to pick up a little information on model railroading this thread did make for some interesting reading, thanks.  Rick

This is a picture I've had for a while.  I have no idea what railroad line it is, but it brings back memories of watching those old engines roll by many years ago.  It was a natural thing to wave to the engineers and the men in the caboose and they'd always wave back too.

Thanks, guys, I appreciate the information.  I put the Harry Potter set up a couple weeks ago because I thought my grandson was getting old enough now to appreciate it.  It's been many, many years since I've had a train set up and running, so I had the plywood cut to match the HP oval.  Now it looks like I"ll have to be getting a full sheet so I can add the extra track.  I guess that's how every new railroad empire gets it's start.  He's already talking about adding more rail cars and buildings too.

I'll probably be stopping back every so often with a new question or two as problems arise.  You've been real helpful, thanks again.

This may sound kind of stupid to most people here, but I haven't a clue, so I have to ask. 

I've got an old Harry Potter set that has the steel EZ Tracks.  My grandson just got a set that uses the nickel/silver EZ Tracks.  Can the steel and nickel tracks be combined to enlarge the present layout?  Also, can two engines be run on the one transformer?  If not, is it possible to double up transformers?

Thanks in advance for your help.
