2mm scale train motorised and given lifting pantographs

[Welly]

Saw this YouTube video of a static 2mm scale model of a Japanese engineering train being given motor drive and lifting pantographs. It does not appear to be DCC controlled but uses wifi module as control. Thought soem here would like to see it.

Fascinating!  A magnificent piece of miniature engineering to do all that in 2mm scale.  I haven't seen stepper motors that small before.

 

I would like to know why he;s using wifi rather than DCC, presumably he sees some advantage that has escaped my notice.

 

It's the first time I've seen infra-red used as a means of transmitting commands from one vehicle in a train to its neighbour.

I've ofen thought the idea we see of carriage lighting being DCC controlled by a spearate DCC decoder in each coach as clumsy and I don't like the "magic wand" system as much of an improvement over "hand of god", and I wonder whether this might form the basis for future developments in accessory control along a train.

I think he uses wifi because standard DCC decoder outputs and commands do not appear to be able to accomodate stepper motor driving?

 

Oh and I don't think DCC can accomodate infra red comminucation between coaches hence another reason to use wifi!
