Are both of these sets ready to go and will just have to be put together, or will they have to have other parts bought to make them work?

thank you.

I'm looking for a goodlooking train that is easy to use and has a nice size track...(less than 6 Feet)... I need this train to use in a display and I wanted it to be easy to use and will stay running all day will it is in the display... i found two here local on craigslist and was wandering what you guys thought would be the best one for the buck.

the first one is: Bachmann HO Scale Train set Alaska McKinnley it looks like it is about the right size but i was wandering how big the cars was?   Here is the link...  http://cincinnati.craigslist.org/for/1585987892.html

the second one is: an E-Z track system.. i think the seller doesn't list much about it but there is a picture of the box on the add.... could someone tell me the size of the track and cars in this one?   Here is the link...   http://indianapolis.craigslist.org/tag/1612718310.html

Any other kinds you think would be good just let me know to.


thank you.
