Wagon counter. It would be limited to 99.
Shows wagon count from signal position.
Would be own setting "show wagon count in ALT mode".
Only works with one/two ways rails ignoring any crossing rails with multiple entrances/exits
Both way wagon block also ignores any crossing rails with multiple entrances/exits. So these both can reach only "next" furthest away signal with limit of one signal. Doesn't count over chain signal
