Why traditional model railways are fine it must no be forgotten that they started off as toys (for boys!) but have grown into a hobby more attractive adults than children
Catering for the younger generations there are still toy trains. Plastic rather than tinplate and battery powered rather than clockwork. Collectively though they provide an interesting branch to railway modelling. Collecting such models is part and part of the Train Collectors Society
Any Make - Any Gauge - Any Age is the motto of the society and a glance at any magazine from the society clearly shows this.
A common example is shown below. Bought new for £1 this model is running on 12mm plastic track and has been tested on Triang TT track. this particular model can be found in a number of variations. Other sets have an oval and points.
