Need to find a safe battery powered 0 gauge sized toy train for a toddler to gain a hands on "This is mine!" connection to model trains. Something with plastic Brio type track, no wires. Any particular brand of which you are aware? Safe is the main theme.
I am in the process of building a 20" high MTH 3 rail add on as a lower shelf to my 2 rail branchline round the wall layout for his later on enjoyment.
What intro stuff have you found good for little tykes?
