Breakdown views

The Costs and revenue section of a proposal shows one breakdown at a time: every cost item, every revenue item and the operator's margin, for one slice of the route in one unit. The model computes every slice once, on the server, when the proposal is evaluated; the switches above the breakdown only choose which pre-computed slice to read. Nothing is summed or divided in the browser.

All slices start from the same annual figures. Every cost is first computed per event — per segment, per stop call, per stabling stay, per shunting move, per coach per year — and multiplied up to a year of operation; every ticket relation (origin, destination, class) carries its annual revenue. A view then decides where each of those euros lands.

Full route

The whole proposal in one figure set: every segment, stop, stabling stay, shunting move, coach and ticket relation, both directions, a full year. This is the view the necessary subsidy and the other headline figures are read from. Nothing is allocated here — each item is simply summed.

By trip pair (shown only once a route has more than one pair, such as a Y-shaped route with two branches sharing a trunk) is the same summation for one outbound-and-return pair alone.

By country

A trip pair's money split by the countries it runs through. The rule is that costs land where the train drives or where the event happens, and revenue where the passengers sit:

Item	Lands in
Driver and crew while driving	each country by its share of the driving time
Driver and crew during a stop, station charges, shunting, stabling	the country of that stop, terminal or siding
Track access	the country whose infrastructure manager levied the charge — a segment crossing a border is priced by each side at its own rate; a separately charged crossing keeps a distance split
Traction energy	the country that supplied the electricity, at its tariff
Coach maintenance	each country by its share of the distance
Coach amortisation, financing, fixed overhead	each country by the pair's distance share
Locomotive lease, cleaning	each country by the pair's time share
Ticket revenue, additional services, catering, service and stockings, variable overhead, margin	each country by the place-km sold on its territory — a Vienna → Berlin passenger contributes to Austria, Czechia and Germany in proportion to the kilometres ridden in each

Country cells partition the pair: their annual figures add up exactly to the Full route figure. Their per-kilometre figures do not — see Units.

By route section

Money attributed to a physical piece of a trip between two of its stops, chosen with the two-thumb slider. Every ordered pair of stops is a section, night stops included, and one section counts both directions over the same piece of track.

Selecting Hamburg – Berlin on a Copenhagen – Hamburg – Berlin – Munich train means:

• every cost that occurs between Hamburg and Berlin — the segments' driver, crew, track access, energy and maintenance, and the stop calls at both boundary stops — in full;
• the locomotive lease for the section's own minutes (driving plus dwell);
• a share of the pair's fleet costs (amortisation, financing, fixed overhead) by the section's kilometres, and of cleaning by its driving hours;
• a share of shunting and stabling by the section's share of the pair's revenue;
• and the kilometre-proportional revenue of everyone on board there — a Copenhagen → Munich passenger contributes the fraction of their fare that matches the kilometres they ride inside the section, together with the service, overhead and margin that ride on that fare.

Sections overlap by construction — the full-length section is the whole trip — so, unlike the other views, section cells do not add up to the route figure. Each section carries per-class sub-cells as well, which do add up to the section's own total.

By stop

Money attributed to one stop call of one direction. Only the passengers who board or alight there count: a through-rider is invisible at a stop, which is exactly what makes this the view for the question what does calling here cost and earn?

Item	Lands on the stop
Driver and crew during the dwell, station charge	directly, from the stop call
Driver, crew, track access, energy, maintenance of the adjacent segments	by the boarding and alighting passengers' share of the place-km on those segments
Ticket revenue, additional services, catering, service and stockings, variable overhead, margin	of the relations that board or alight here, in full
Every other cost (fleet, lease, cleaning, shunting, stabling)	by the stop's share of the route's place-km, half at each relation's origin and half at its destination

Stop cells partition the route: over all stops of both directions they add up to the Full route figure.

Units

Every view can be read per year, per operating day, per train-kilometre, per available place-kilometre or per sold place-kilometre. The two time units simply divide by the year's operating days; the three per-kilometre units divide by the slice's own kilometres: a country cell by the kilometres run in that country, a section by its own length, the full route by the whole cycle. That is what makes a per-kilometre figure comparable between slices — the Dutch track-access rate reads as the Dutch rate, not as the Dutch charge spread over the whole journey — and it is also why per-kilometre figures of different slices cannot be added: rates over different denominators do not sum. Annual and per-day figures stay additive.

The class switch reads the same slice for one accommodation class: its own ticket revenue and passenger-side costs directly, and the train-level costs by the class's share of the train's place-km. Class cells add up to the "all classes" cell of the same slice.
