Residual slot marketplace

List unused capacity, discover available slots on your corridor, and settle reservations through Polar — without switching between national IM portals.

Slot lifecycle

Publish a slot with corridor, time window, and price. Buyers search, reserve, and confirm. Infrastructure managers retain audit trails for every transaction.

Polar settlement

Payments flow through Polar Checkout — no card data touches RailSlot servers. Webhook confirmation updates reservation status automatically.

Operator-grade trust

Every listing ties back to validated topology and capacity bands. No ghost slots from spreadsheets.
