Demurrage, detention and storage tariffs are set by each carrier, terminal and contract and change frequently. The preloaded figures are editable industry-typical examples, not quotes — always verify against the current published tariff or your service contract before paying or disputing an invoice.
Canadian National is North America's only transcontinental railroad, running Pacific–Atlantic–Gulf with major port feeds at Vancouver, Prince Rupert and Montreal. Hold its equipment past free time and the demurrage ledger starts: this calculator reproduces the math per railcar so a slow unloading week is priced before it's billed.
About Canadian National Demurrage Calculator
Canadian regulatory practice differs from the US — demurrage disputes north of the border run through the Canadian Transportation Agency rather than the STB. Defaults model a realistic scenario (1 free day, then $75 ×2d, $145+); a 5-day hold costs $440 per railcar, and fleets multiply it fast. Demurrage management on rail is pipeline management: match inbound flow to unloading capacity, watch constructive placement (the clock can run while cars wait in the serving yard), and audit the monthly statement against your own records — carrier-caused bunching is both common and winnable.

Frequently asked questions
How is Canadian National demurrage calculated?+
Held time minus free days, priced per day per railcar. With the defaults (1 free, then $75 for 2d, $145 after), 5 days held = 2 × $75 + 2 × $145 = $440 per railcar — multiply by your fleet size for the statement-level number.
Who regulates CN demurrage disputes in Canada?+
The Canadian Transportation Agency (CTA), which can review charges and service obligations — the Canadian analogue of the STB path. Cross-border moves can implicate either regime depending on the haul; for a dispute, first fix which country's tariff and regulator govern the cars in question.
What is constructive placement?+
The railroad's right to start the clock when cars are ready for delivery but your facility can't take them — they sit in the serving yard 'constructively placed' and bill as if spotted. It's the most disputed concept in rail demurrage; the defence is documented unloading capacity and evidence the road's own bunching created the backlog.
Do demurrage credits offset debits at Canadian National?+
Depends on the road's current tariff — traditional credit/debit offsetting has been curtailed across the industry since 2018, which is exactly what shipper groups contested at the STB. Read the credit rules in the current document rather than assuming last contract's netting still applies.
