Well, the other day my K-line power supply gave up and died. It has been acting flaky for awhile now, and the whistle function never worked right (I bought it used). So I took down the O and put up the HO and Z till I get a new power supply, at which time the O will be put back up.
Every night I ran the O gauge layout while holding my 11 month old, and she would lay down on me and fall asleep. When I showed her the HO layout, she yelled, gave me a scowl, and slapped me-guess she likes the big trains! My 5 year old likes the HO better, because it has roads already on it for his matchbox cars, though he does miss the barrel loader! My 3 year old girl really likes the Z scale-it is a cute baby train . My wife, who has always been a fan of HO realized after seeing the HO layout why I like O and now feels like HO is too small.
So, I guess I will be putting a new power supply in the budget.
