Greg,
No offence, it was my intention only, to tell as much as possible about the "whole" story on rail connections, especially for those who are new in the LGB
May i ask you two questions related to the not intended subject?
1 Can you tell me the market name of that nickel grease and what color is the "prototype" color?
2 Can you explain why use plastic clamps on switches especially? Or do you mean the brass Massoth connectors? The latter are indeed especially handy when a switch has to be removed for maintenance , since by using these connectors both tracks adjacent to the switch do not have to be moved.
