What TTR readiness actually means

The Timetabling and Capacity Redesign (TCR/TTR) programme changes how European railways allocate path capacity. Instead of annual-only booking windows, operators face rolling, residual, and ad-hoc bands — each with different lead times and pricing dynamics.

The four band types

Annual paths remain the backbone for stable flows. Rolling paths allow seasonal adjustments within the year. Residual capacity opens when IMs publish unused slots. Ad-hoc covers urgent requests outside the normal calendar.

Readiness is not about having a spreadsheet for each band — it is about systems that query, validate, and book against the correct window automatically.

Why manual processes fail

Operators spending hours in national IM portals miss residual slots that appear and disappear within minutes. Cross-border corridors multiply the problem: each IM has its own interface, data format, and booking rules.

RailSlot unifies topology, TTR calendar validation, and route physics in one API — so your planning system asks "is this path feasible in this band?" before you commit.
