Yet another question:

If there were more than one Lautewerk at a station for more than one line, was each Lautewerk at a different tone (e.g. high - medium - low: beyond the one or two bells that each lautewerk had) so they attendant knew which line was the active arrival? Since I presume the codes mentioned above are/were universal, how would one differentiate between multiple lines?

Thanks in advance!

Peace of the season,

Jim
