I had to collect reimbursement invoices for a Xi'an high-speed rail trip and found that the timing matters. The ticket itself showed the trip details, but my finance team needed the official rail invoice with my passport name and the route. I was able to collect it from the station service window after arrival, using the passport tied to the booking.
The service window asked for the order details from the rail app and checked the travel date. The staff printed the invoice quickly, but the queue was mixed with people changing tickets, so it took longer than the actual document work. I also asked for separate invoices for each leg because my company records outbound and return travel separately.
For anyone traveling for work, do not leave this until you are rushing to a meeting. Build in a buffer at the arrival station or collect it during a quieter station visit. Are there any reliable app-based options that work well with passport bookings?
