Hi All, This may be me not doing things right, but on a number of occasions when running a service, the Class 166 suddenly starts to slow and stop despite the power being set to full. This is NOT due to AWS (it has happened on track in between signals), nor is it the DSD (driver awareness) as I cancel as soon as I hear the beeping. Has anyone else experienced this? Once stopped I can sometimes get it going again and sometimes not. It is not consistent.
