Just looked for the RhB loco diagrams (lokdienste) - previously (until a couple of days ago) freely available on RhB Bahn website:
"the lokdienste are now exclusive to members of the RhB Club"
OK I thought - maybe not so bad, how do I join...
looked further on and clicked on RhB Club link...erm...
Club annual membership single person over 16 years - CHF89...
