A couple of the points became a bit iffy over the weekend, needing repeated presses of the push buttons - and a burst from the CPU - to throw.
Another one had a freak failure of the shaft connecting the motor and the point.
All those dodgy units have now been replaced.
It’s remarkable that we should have so many fail in one weekend given how those installed on Dduallt have done nearly 30 years.
One of the rotary switches to select the roads has been changed - a big job with so many connections to be unsoldered and replaced - and there were a number of failed LEDS to be renewed.
