Thank you hoeij, yes. the regular tables would be better. the reason I use 'kids' train table because my
sons could play them too. and we do not have that big room.
I am really curious about the display setting. so most of people just put layout in the ground? I do not
feel comfortable somehow..
Thank you soc399 for the Andy's link. it is really awesome. hmm, I will consider do a two level thing. (I do not have many trains actually, and my 4.5v battery box stopped working :( )
