Well I observed the whole incident! There seemed to be a certain nonchalent use of two locos where one was seen to chase the front runner but not adhere to the signalling policy. I hasten to add this was the result of Bigjack shay not travelling even with the customary slow speed that is required of such a loco

. DCC shay stuck on notch 1, Battery porter on notch 2

....only disaster would eventually happen! Well I was in charge of the controller and...ahem .......... that was the the problem.....
Many thanks to all those of you who came and have posted such goodly comments. Many thanks to you for attending to our little train event especially to Richie and Sara who came for the weekend. I was really up against it this time due to the damage from tree-fellers and a years neglect and Richie was a star in helping me get the line cleaned and working. After much worry about weather, and problems getting everything just so, it turned out to be a glorious day which Lorraine and I thouroughly enjoyed. Last guest, Tony, left at 9.00pm!
Thanks to you Richie, Sara, Gordon, Bigjack, Mary, John, Jon, Stuart (Marshman), Tony, Edward? +two +wife, ...I will now go and collapse...or have another beer.........yes another beer I think
