I've got three separate Kato 22-018 controllers (running Kato HO & N plus Tillig TT) but I need more space between them so I wondered if Kato sells an extension lead for the power input wire originating from the power pack or transformer? Or is it a question of going to an electrical store and getting a generic equivalent? Or is this unwise electrically? In addition does Kato HO & N manufacture an uncoupling track which would be suitable for the common European Roco hoop type couplers? All I have managed to find so far in the catalogue is a magnetic type uncoupler track. Could anyone suggest an alternative?
