Significantly in Germany, relations of this type are used to aggregate (combine) connected train tracks between two endpoints that are maintained as an operational unit into a single relation. There is a similar and much more widely used route=railway relation, which is used for larger infrastructure segments potentially stretching over several route=tracks relations. These relations are not widely used; use with discretion or not at all if that is the regional convention for you, as route=railway suffices for most of the world's rail aggregation in OSM.
For lines describing the travel of trains, usually for passenger services, use the tag route=train.
Tagging
The ways (railway=rail, railway=disused, railway=abandoned or railway=razed) are collected in a relation with the following tags:

All rails that are part of the track should be members of the relation. In contrast to train routes, the stations, platforms, and other non-track object should not be members. Removed tracks (railway=abandoned or railway=razed), that were once members of the track, should get the role „historic“.
On multi-track sections, you may add the side of the track by using left, right, A etc. member roles on the ways.[1]
Country specific
Relations of this sort are a minority of rail relations; there are "low thousands" of route=tracks, yet "tens of thousands" of route=railway. Routes tagged route=tracks seem to be found in Central/Northern Europe, Germany especially, because of how three relations, including the usually-extra of route=tracks are used to describe rail, rather than only "the other two," (route=railway and route=train), used much more frequently to group rail more simply (as using only two route relation types is simpler than three by including route=tracks relations).
There is also this thread in our community forum, which also expands consciousness of "how big is too big?" (of rail aggregation relations) and "what, exactly do and don't we aggregate?"
There is some sharpening up of focus (with better awareness) of how these topics (rail grouping among OSM data structures) interact. Germany uses tracks, many (most?) other regions use route=railway and route=train relations only (or largely so, with only rare "incursions" by route=tracks relations). With input from more countries / regions we better characterize this. If others in other countries / regions could additionally add below how things are tagged / aggregaged in your area, that can only help deepen the dialog.
Germany
In Germany route=tracks is used for VzG line numbers (four digit, unambiguous identification of a railway line), while route=railway is used to refer to timetabled route numbers (three digit, Kursbuchstrecke referring to a route of passenger services).
United States
In some countries like e.g. the USA route=tracks relations are not used, only route=railway relations are (as "collections of rail elements"). Moreover, a route=railway in North America (and most of the world?) does not imply or mean anything about passenger rail service on these collected members, as it does in Germany.
