Branch Meeting Thursday 25 September: National Train Control VHF Radio Communications
- Wellington VHF Group
- The ONTRACK National Train Control Centre at the Wellington Railway Station communicates with the locomotive drivers out on the track using a VHF radio network. This month we are fortunate to have John Skilton, Manager Signals and Telecommunications Engineering at ONTRACK, and Stu Lusty from Kordia, coming to speak to us about the upgrade of this train control VHF radio system and the new technologies that are being employed. Members and guests are welcome to come along to what should be an interesting and informative evening.
