This one surprised me and discusses the method used to control the layout. I brought this into the mix not so I could discuss the merits of DCC as compared to batteries and RC but more to express a thought about the shear size of the system used to control a layout so small.
Whatever method of controlling the trains the system itself should be in line with the layout in terms of:
How much space does it require?
If the layout is small, for example around four square feet, should the controller be some massive big block like the old H&M or MRC controllers? My current is a small handheld throttle that uses an external transformer. I like that it takes very little room to store between sessions and most of it can be easily concealed within the footprint of the layout itself. I thought of this when looking at the little Sprog 3 DCC command station and how it takes relatively little room and could be completely incorporated into the layout – almost invisible to the viewer.
And about as complicated…
Does a four square foot inglenook-style layout really need DCC controlled turnout motors and even sound? Is the viability of these requirements a function of the size of the layout? It seems so simple that it almost doesn’t even need to be said but then why not since we’re here anyway.
