Late Running

Friend and former colleague R has brought his self-made train model over for a test run on the FWR (i.e. our garden railway).  Most of the testing is scheduled for tomorrow but as the model has lighting he wanted to get some twilight shots.

Testing seems to have demonstrated that the radio control isn't doing quite what it should.  

True to our combined 70 years of high tech engineering experience, we tried turning it off and on again; then wiggling it bit.
