Thanks Kingfisher, you beat me to answer the question. The practicality of removing the bogies would depend on the length of wire and adequacy of the connections. Any movement will potentially weaken the connections and could result in wire disconnection.The bogies are electrically active and are connected by fine wires. The instructions that come with the loco advise against removing the bogies because of the fine wire connections. The larger diameter replacement bogie wheels supplied with the loco can be filled without removing the bogies from the loco.I don’t know why the SRM 10 class bogie pickups were not wired, perhaps it was decided that a connection to the loco would interfere with ride and tracking of the truck? The pickups are there, from both sides, with a split axle, but no electrical connection to the loco. They might act as suspension but definitely not as centering springs. Anyway, this is the Austrains thread and I’d like to know whether the C30 bogie pickups are active, and if so, how are they connected? Thanks.Could they act as centering springs?I don't understand why they'd put pick-ups on the pony trucks which serve no purpose?????
Regarding electrical pickups, are the bogies wired to the locomotive, and how is this done? In the case of the Southern Rail 10 class there are double sided pickups fitted to the pony trucks, but they are not wired to the loco, giving electrical pickup on the drivers only.
I have had this happen on a few connectors between engine and tender where the wire was improperly attached to the connector, and after a few maintenance sessions a wire would separate from the connector. Yes, I was very careful not to stress the attachment points.
