[Tagging] Rail segment in a bike route

This issue is the same for routes for other modes of transport, especially
hiking.I know a hiking route using a bus transfer through a tunnel. I know
one in Switzerland using a train through a tunnel but only in winter. I
know one using a bus transfer for all cycling and hiking routes over a 30
Km long dyke. And lots of ferries over rivers and lakes.
I know canoe routes with foot sections (portage).

I would keep the solution as generic and as simple as possible.

As it happens, a basic functional role set has recently been approved for
such routes.It assigns a rol to approaches, excursions, alternatives and
connections between routes.

I was thinking about adding a role "transfer", to be assigned to a member
relation. The relation that gets the role "transfer" is a route relation of
a different transport mode. It's all the information you need, so there is
no need for transport mode specific roles.

There is one complication to be considered: the different type of roles
cannot be combined in one relation. Especially for cycling, a particular
way of the route could have the forward|backward role, belong to an
alternative|approach|excursion|connection, and belong to a transfer
section, all at the same time.
A relation member cannot have the forward|backward role, but it could be
both transfer and one of the approved basic role set.

This complication can always be solved within a relation hierarchy, though.

Best,  Peter Elderson
