Hm nice vid but a little confused with the signalling, on the first lap both signals are off. But after the first circuit the right hand one after an edit is at danger. So what is the logic for the signals? To tell which way the point is facing, but they are clearly not interlocked with the point as if they were both could not be off when the point is set to the left (right when facing direction of travel). Confused.com me is.And the Shay comes out to play too. Max
