@dunnyrail Hi, so far, so good with the CS3, the visualisation and touch screen is very clever for setting points and signals; wiring is oh so simple. It’s also easy to see the sound buttons, rather than having to remember code numbers. Most of my locos are 2000 onwards so they have transferred over fairly seemlessly.
But, and it’s a big but, the iPad type interface does lack the satisfaction of an analogue switch being thrown (The reassuring clack of the switch, and click of the point). Perhaps it’s a a bit too slick, and removes some of the enjoyment and intimacy - for want of a word - of running a layout. I keep the old LGB MTS III as a backup.
