Train set help!

[tbtf]

DD 2.5 will happily play with trains all day, I love it and want to encourage it / join in.

We've got a small set of brio knock off from tesco, and a circular G Gauge track with a battery powered noisy Christmas train.

Should I:
1- buy another brio sized wooden set, and a battery powered train

2- start a Playmobil collection, from ebay as don't think they sell the train sets any more. Not interested in the Playmobil 1.2.3 sets

3- start a proper G Gauge set for myself and let her look at it once in a while

Get more brio

Tomy Trackmaster is the one to get. Mine played with this from aged 2 to about 12. It's not so 'babyish' as brio so it lasts longer yet it is robust enough for a youngster. Buy the track on ebay - it's blue plastic so easy to spot. Lots and lots of choices of trains. Only downside is that you need batteries.

Brio (or fake) DD's loved it until 8 or so, sold of for substantial sun then

Just keep extending the brio for another couple of years. You can buy battery powered locos and get all kinds of accessories (working cranes, stations, signal boxes, engine sheds, etc). We still have huge amounts of the stuff. You'll know when your DD gets fed up of it. Our DS built ever larger and ever more imaginative layouts all over the house - I think he enjoyed planning and building new layouts more than running the trains.
