Travel expenses and disbursements in rail operations

What is digital expense management, and why is it so critical?

Travel expense software for railway operations maps the collective bargaining allowances, surcharges, and statutory meal allowances that apply simultaneously to train drivers, technicians, and field teams, thereby automating calculations that would otherwise have to be done manually by the accounting department.

This calculation is rarely straightforward in the railway industry. Local and long-distance allowances, assembly surcharges based on collective agreements, and the tax office's three-month rule all overlap. At the same time, train drivers and technicians are often on the road for days without access to an office, a printer, or even a fixed desk.

This article shows where the travel expense process in railway operations most frequently fails today, how a software-based solution correctly handles these cases, and how to determine if investing in such a tool is worth it for your company.

Why travel expense management in the railway industry is more complicated than elsewhere

In most industries, it is sufficient to correctly apply the statutory meal allowances set by the Federal Ministry of Finance. In railway operations and assembly, a second layer is added: the collective bargaining agreement, which includes its own types of allowances and surcharges and is interpreted slightly differently by every company.

An employee may have multiple work locations in a single day: a construction site in the morning, another station in the afternoon. Each of these locations can trigger a specific type of allowance, and each allowance has its own tax treatment. If a location is forgotten or incorrectly assigned, the final statement will be inaccurate, and no one will be able to immediately identify where the error lies.

Local and long-distance allowances, assembly surcharges, and the three-month rule

Two types of allowances define rail and assembly operations: local allowances for shorter distances and long-distance allowances for further travel, sometimes supplemented by additional assembly surcharges depending on the site or track. Both regulations must be mapped in parallel with statutory flat rates.

Currently, for business trips without an overnight stay, a tax-free flat rate of 14 euros applies for absences of more than 8 hours, and 28 euros for a full calendar day (24 hours). Arrival and departure days for multi-day trips with an overnight stay are set at a flat rate of 14 euros. If a company pays collectively agreed amounts beyond these statutory limits, as is common in the rail industry, the excess portion must be booked to a taxable account, separate from the tax-free portion.

In addition, there is the three-month rule: if an employee works at the same site for at least three days a week, the tax-free meal allowance is forfeited after three months of activity there, unless the activity is interrupted for at least four weeks. With frequently changing construction sites and projects, this is almost impossible to track without a system.

Where the process fails in practice today

Many rail operators and assembly companies still work with Excel spreadsheets, taped-on paper receipts, and timesheets that are submitted separately. As a result, travel expenses and disbursements reach the audit department through many different channels, which complicates oversight and delays the audit itself.

This is particularly noticeable with decentralized teams. Technicians on construction sites and train drivers on the tracks rarely have the time or the technical capability to submit their travel expenses via an office computer. Receipts are therefore often sent via WhatsApp, submitted on paper, or simply lost because the effort seems too high. In one real-world case, a receipt went through internal mail four times—from submission to distribution to forwarding to the supervisor—before it could even be processed. It can take weeks for a receipt to reach the accounting department this way, especially for projects that span longer periods.

The consequences for accounting and finance

For accounting, this means that meal allowances and collective surcharges must be checked manually, often without complete information on how long a person was actually traveling or whether the three-month period already applies. Errors must be reported back to employees and corrected, which further delays the closing process. For finance managers and CFOs, on the other hand, it is difficult to track how far the monthly closing has actually progressed as long as a relevant portion of travel expenses has not yet been finally audited.

Practical example: What native compliance looks like in the system

The difference between manual and software-supported accounting is most evident in a specific case. If an employee travels to a construction site for seven hours, no tax-free flat rate applies, so a collectively agreed allowance amount must be booked entirely to a taxable account. If the same person travels with the same type of allowance over several days, they exceed the eight-hour threshold, and the same daily amount is instead assigned to the tax-free account. Only the duration of the trip determines the correct accounting, not the type of allowance alone.

‍

In software that incorporates this logic from the start, the employee simply selects the appropriate allowance type when submitting, while travel duration, destination, and surcharges are calculated automatically. In the end, the accounting department only sees the result and merely has to confirm it, rather than calculating it from scratch. Special cases, such as a subsidy that only applies to the first two days of a three-day trip, or a trip abroad for which general BMF rates apply instead of the collective agreement, can also be cleanly separated in this way.

What changes concretely for employees, accounting, and finance

For train drivers and technicians on the move

Instead of collecting receipts, taping them down, and filling out timesheets by hand, employees can photograph their receipts directly with their smartphones and submit their travel expenses via a mobile app that automatically pulls destination addresses from map services. Reimbursements are processed promptly rather than waiting until the end of the month.

For accounting audits

When meal allowances and tariff rules are calculated correctly at the time of submission, the review process is noticeably shortened. With Circula, currently 54 percent of all submitted expenses are ready for export to accounting as soon as they are filed, without the need for manual correction. Fewer queries mean fewer interruptions to the daily accounting workflow.

For finance and controlling

Instead of waiting until the end of the month to see how much rework is pending, travel expenses are visible in real-time, broken down by project or cost center. This provides planning security for month-end closing and reduces the risk of errors only being discovered during a tax audit.

Does investing in travel expense software make sense for your company?

Not every company needs a new solution immediately. However, some signs indicate that it is worth taking a closer look: a growing team that is outgrowing existing Excel or paper-based processes, multiple parallel tariff regulations that are becoming difficult to manage manually, decentralized employees without regular office access, or a tax audit that has already highlighted gaps in your current documentation.

Before making a decision, it is worth taking a structured look at your own processes: Which types of allowances and surcharges currently apply, how are they recorded today, and where does the greatest manual effort arise? In practice, a three-step process has proven effective: a workshop with all involved departments to clarify actual requirements, a product demonstration using concrete case studies from your own operations, and an IT meeting to discuss integration with existing financial accounting systems. On this basis, a project can usually be implemented within a few weeks.

Our webinar shows how these BMTV cases are specifically calculated in the system "Expenses and disbursements in rail operations: finally accurate, finally automatic" using several live examples, from simple day trips to combinations of long-distance allowances and additional subsidies. The recording is particularly suitable for finance and accounting teams who want to see how their own tariff and allowance rules are handled.

Conclusion

Travel expense accounting in the rail industry is complex because tariff-based allowances and statutory meal per diems apply simultaneously, and because a large portion of the workforce does not work at a desk. Software that maps this logic from the ground up noticeably changes the accounting process in three ways: employees submit travel expenses on the go without detours, accounting reviews instead of recalculating, and finance keeps an eye on the month-end closing in real-time. Whether the investment is worthwhile for your company is best judged based on your own tariff rules and actual team structure, rather than a general rule of thumb.
