# Calculate Station Transfer Buffers for Connecting Rail Journeys — Free

Booking complex multi-leg rail journeys across European or intercity networks often looks feasible on printed timetables, but navigating sprawling concourses and climbing stairs between distant platforms erodes transfer windows. Enter your arrival and departure times, platform walking estimates, and contingency targets to identify the bottleneck transfer buffer.

**Free and complete.** This guide is a standalone free tool — no account, no card, anywhere. The only paid option is one optional extra outcome: $4 one-time. Nothing in the free tier is gated.

## Who it's for

Rail passengers, international travelers, and trip planners organizing connecting train journeys.

## What's free

- one complete unwatermarked rail-connection strip run in the app
- three labeled samples and unlimited article-demo calculations
- complete result text and a user-triggered input-state link

## Optional paid add-on

**$4 one-time.**

- unlimited subsequent rail-connection strip app calculations after a local convenience signal
- print the rail-connection strip with visible assumptions and its safety boundary
- CSV of the displayed minutes and row workings; conditional estimate uses your manual-retyping minutes
- five local reading summaries (headline/count/time), not saved full inputs or cross-device backups

## Sources & verification

- Tool: GratisAI local-first instrument (no key, no account)
