Not precisely flat, but with very shallow grades, by definition. Regular
railroad engines (as opposed to cog railway engines) can't climb steep
slopes. So, if you are looking for a route without steep grades, a former
railway is a natural choice.

Do I understand you correctly: We should map abandoned railways because
we lack a good source of elevation data?
That sounds like a very strange proposal to me. Perhaps the wiki
documenting the "abandoned" value should be amended by "not to be used
for abandoned mountain railways, because cycle routers will prefer
routing along abandoned railway lines under the assumption that they
must be flat"?
