Taming the Tamworth Team Society trips away often provide time for the tour team to enjoy local sites and spend off duty time with like minded members. While their activities are mostly low key when a few “characters” get together their activities can go off the rails quickly. One such example was the Australia Day charter to Tamworth where Train Manager Steve Davies had to take matters into his own hands and whip the team into shape. Thanks to a locally procured stock whip even the wildest members of the crew soon fell into line although it was noted that old habits die hard with the resident Driver Trainer seizing the opportunity to try and settle some old scores with his former CityRail colleague on Tamworth platform.

Ron’s apprentice? Members who have visited Paterson recently can not help but comment about the attractive depot surrounds, the results of the hard and expert efforts of Depot caretaker Ron and long time gardner Barrie Kingsford. While the beautifully presented grounds are still a work in progress the variety of healthy plant life is also obviously appreciated by our animal friends with bird species including currawongs, lorikeets, galahs and native pigeons regularly gathering to feast and sing from the trees and the SM’s cottage verandah. In addition to his feathered friends, Ron has also played host to other visitors of late including red bellied black snakes sunning themselves before their winter hibernation and recently a quick moving wallaby. “Skip” has been seen several times tending to the grassed areas of the yard prompting Margret Pantlin to capture the accompanying photo and ask if he has been engaged as Ron’s apprentice?

Saturday With showers in the area, 621/721 departed as 7R00 Paterson on time and headed to North Strathfield for the Epping Model Railway Club’s two day tour of the Metropolitan Goods Lines and Tahmoor Colliery.
