i’ve asked about shortcomings. shortcomings suggest a need that could be fulfilled with some new idea (technology)
there was oviously a desire to be able to control multiple locomotives on the same track. cab control was limiting and requires a lot of wiring.
before DCC, people were atempting to use higher frquency demodulators in locomotives to be able to control them. the problem would be that the frequency for each loco was fixed and throttle would have replacable tuning circuits
I don’t know how they intended to control the motor. i heard about this in college in the early 80s before processors and digital control using h-bridges took off.
on the other hand, new technology might lead the way. Blunami is an example. but it hasn’t taken off even though it seems to fulfill a shortcoming.
but not everything needs to be technological
as i’ve said, economics is also a driver. Foam benchwork is an example that simplifies construction
new material is another driver, ground foam was a step up from lichen and dyed sawdust.
ready-to-run is another driver that lead to manufacturing of higher detailed locos in china. Plug-and-play is another driver that makes using technology simpler.
another driver may be reliablilty. Presuambly one motivation for using batteries is reliable power that can replace the use of keep alives and avoids the need to keep track clean
is better performance due to the availability of metal wheels from venders like Intermountain.
again, i think if you want to know where the hobby is going you need to look at what it is missing, its shortcoming
