European railway data standards

We implement the standards European railways run on.

CET4Biz helps infrastructure managers, railway undertakings and their technology partners meet European interoperability requirements — from first audit and interpretation, through development and integration, to long-term operation.

Trusted by European railway organisations and their technology partners.

Capabilities

Three things, done properly.

  • Railway standards and conformity

    We know TEL TSI (formerly TAF/TAP TSI), OSDM and the surrounding European regulatory landscape in detail, because we have implemented them for the organisations that define them. Audit, validation and the support that gets you through assessment.

  • Software engineering and system integration

    Provider-independent, modular, built on microservices. We make systems that already exist work together, and we build the ones that are missing.

  • Consulting and project leadership

    You set the target. We produce the plan, run the feasibility check, review your processes with your people, and hand back documented results.

Rail expertise

From regulation to running system.

European rail interoperability requirements are demanding, and they keep moving. TEL TSI consolidates what the industry knew as TAF and TAP TSI; OSDM governs how offers, orders and tickets are exchanged. Reading the regulation is the easy part. Turning it into data models, messages and processes that survive an audit is where projects fail — and where we work.

  1. Audit and gap analysis

    We assess your current data, messages and processes against the applicable standard and give you a prioritised list of what actually has to change. Where the regulation is open to interpretation, we tell you how the sector reads it and what your peers have implemented.

  2. Conformity checks and validation

    Systematic checking of messages, data structures and processes against the current, versioned standard — with findings explained in terms your engineers can act on, not just a pass or fail.

  3. Certification support

    We do not issue certificates. We prepare you for the people who do: assembling the evidence, closing the gaps the assessment will find, producing the documentation the process demands, and staying alongside you through it.

  4. Project management

    Experienced leadership for multi-party programmes, including the coordination between infrastructure managers, undertakings and suppliers that these projects always require.

  5. Development and integration

    We build the validators, interfaces and services, and integrate them with the systems you already run.

  6. Operation and maintenance

    Standards change. We keep what we built conformant as they do.

If you are starting a TEL TSI or OSDM programme — or recovering one — a first conversation costs you an hour.

Data you can decide on.

We handle data gathering, storage and analysis, and we are honest about what is realistically possible with the data you have. Business intelligence for decision support, machine learning where it earns its place, and AI integrated into day-to-day operations rather than bolted on for show. Provider-independent, as always — we recommend the tool that fits, not the one we resell.

Group and track record

A services company that builds products for a living.

CET4Biz is an operating company of Bestforent Holding, a Vienna technology group that develops and owns its own software platforms. Our engineers have worked on both of them. That is an unusual thing for a consultancy to be able to say, and it changes what you get: the standards we apply to your system are the ones we apply to software the group has to run, support and answer for over years.

Bestforent Holding owns both BrainTrainAI and MyVipGuest. CET4Biz is an operating company of Bestforent Holding, and its engineers performed work on both platforms. CET4Biz does not own either platform.
  • BrainTrainAI

    brain-train.at

    An AI-supported knowledge, validation and governance platform for heavily regulated industries, owned by Bestforent Holding and developed with funding from the Austrian Research Promotion Agency (FFG).

  • MyVipGuest

    myvipguest.com

    A white-label loyalty engine for hospitality, retail and luxury brands, owned by Bestforent Holding and in production across Europe.

Both platforms belong to Bestforent Holding. What belongs to us is the engineering — and the habit of building things that still have to work in five years.

Twenty-five years of getting complicated projects finished.

CET4Biz GmbH is based in Vienna and is part of Bestforent Holding. We are a small, senior team — the people you meet in the first meeting are the people who do the work. We are provider-independent by design, which means our advice is not shaped by a licence we need to resell, and our architectures are modular so you are never locked into us either.

A short call is usually enough to establish whether we are the right partner for your programme. If we are not, we will tell you, and we will usually know someone who is.
