I have the Cargo Train set (60052); the railway is very basic - it's an oval with two switches connecting a brief side track.
On the box, there's an illustration of what can be done by adding the high speed train set (60051), but it's still very basic, as it only adds another oval to the track.
Does anybody have ideas about making a fun/interesting railway, where one can play in a more elaborate way? Right now, the only thing I can do is use the switches and nothing else.
I'm OK with buying any other (type of) set, including Technic, if that would do the work (e.g. remote-controlled switches etc.).
Thanks!
