In 2018, the UIC Sustainable Mobility Expert Network launched the "Sustainable passenger railways and door-to-door solutions" global project with the aim of developing guidelines based on cooperation between UIC members, stakeholders in the railway sector and experts in sustainable mobility. The goal is to define the characteristics of door-to-door mobility with particular attention to integrating new vehicle-sharing and ridesharing services and new digital technologies in the railway transport sector more generally in order to provide a more customer-oriented service.

The final output of the project will be a document: “UIC Door-to-Door Solutions - Guidelines for the Railway” targeted toward railway operators and infrastructure managers/station managers. This project is being conducted with the support of the Foundation for Sustainable Development in Rome, Italy.

Door-to-door project framework

Door-to-door solutions in the rail sector refers to the combined use of rail and other modes (or means) of transport in the same journey. Door-to-door solutions promote multimodality, seamless mobility and a rail transport service that is more customer-oriented and therefore able to increase market share for railway companies. The concept of D2D is driven by the growing trend towards digitalisation.

All the actions currently available for a railway company to offer its customers a combined and seamless mobility service that INCLUDES the RAIL TRANSPORT service between the different travel solutions used during the entire journey.


For railway companies, the development of new, innovative door-to-door solutions is a key factor in becoming competitive with other less sustainable modes, particularly personal cars. This means, for example, giving customers the possibility to choose a single travel solution, even if it involves multiple transport modes or is provided by various mobility operators, through a single user-friendly interface to plan, book and pay for the entire trip.

The objectives to be achieved through the development of D2D are:

  • modal shift from less sustainable modes to railways;
  • improving interchange between rail and other modes of transport (in particular shared and non-motorised transport modes);
  • promotion of a seamless travel experience;
  • making railway stations into mobility hubs.

Project phases and timeline

The project will be implemented in three stages and is spread over a period of three years.

Concept - The goal of the conceptual stage is to set a theoretical framework, establishing a definition of what door-to-door solutions are as well as a shared vision of why and how best to integrate these new customer-centric transport services as part of a sustainable mobility approach.

Engagement - The project should build on experience already implemented by railway companies by analysing them and disseminating their results among UIC members. The main purpose is to collect and analyse the various types of integration both between transport modes and transport services. The main focus of this collection is to select digital D2D solutions such as, for example, the implementation of new technologies, new services and new business models that demonstrate efficient and effective results in terms of improving the service provided by railways and shifting from less sustainable modes of transport to rail.

Dissemination - A proposal for “UIC guidelines on sustainable passenger door-to-door solutions” is being drafted on the basis of the results from the previous phases. The guidelines focus on the following main topics: technologies/services/business model of “door to door” solutions, international collection of best practices for door-to-door solutions and experiences involving railway companies, KPIs in order to monitor the implementation of solutions by market share gains and positive environmental impacts, and recommendations for a valuable door-to-door business strategy. The final report provides a summary of the work carried out and the overall conclusions.

Passenger door-to-door solutions: preparatory study

View PDF

The present Preparatory Study is the first deliverable of the Door-to-Door Project.

The first chapter has the function of explaining how the door-to-door theme is central in the shared or collective mobility system, contextualizing it from a technical and historical point of view. It starts from the rise of the personal car, product of the industrial revolution in the early 20th century, leading people back to the movement continuity that had been lost with the advent of railway after the era of "the passage of man and footsteps of the horse ". This analysis aims to clarify the boundaries between personal mobility and shared mobility, through the history of the leadership achieved by personal mobility in the transport sector thanks to some particular technical characteristics that made it a success. At the same time, the main environmental and social repercussions of this epochal transition are underlined.

The second chapter sets out the most important ongoing trends leading to changes in the transport sector, changes comparable to those that occurred during the advent of mass motorization. Among these, the digitalization stands out: the 21st century technological revolution is able to challenge the supremacy of personal cars in favor of shared transport once again.

To better understand this aspect, the third chapter of this report analyzes the innovative shared mobility services enabled by new digital technologies and new behavior. The report will also discuss the importance of accessibility, urban planning and urban development. Defining which such services are, how they work and their characteristics will be the principle questions in order to shape the boundaries of the present shared mobility ecosystem, in which rail services are an essential component. The detailed analysis dedicated to the so-called innovative shared mobility services will lead not only to understand the potential of these services but also to bring out the enormous potential linked to their integration with traditional shared mobility services. In this chapter, we define what the door-to-door digital solutions mean for rail services and what the objectives related to their development are. In particular, we focus on the positive environmental consequences given by actually making the railway a choice of seamless mobility and filling the first and last mile between one train station and another.

The last chapter of the study outlines the framework of the main areas of intervention of door-to-door solutions, what are the strategic lines of intervention to enhance integration with other services and other actors of shared mobility considering also the importance of public policies and investments, trying to bring out risks and opportunities that the sector could face in the future. This chapter aims to bridge with next year’s activity of the Door-to-Door Project, also including a brief summary of some good practices presented by railway operators during the first UIC Workshop in Warsaw on this topic.

Digital door-to-door solutions - 10 Guiding principles for railways

Technological advancements in the field of digitisation and internet services are profoundly changing all areas of human society, it is changing our economy, our society and the relationship between the individual and the world around them. This technological transformation is already deeply affecting today’s transport systems and is bringing a new mobility paradigm able of guaranteeing more accessibility, better management of public space and greater environmental sustainability. Smart mobility will improve the outcomes and reduce negative effects from transport, addressing several complicating factors in the meantime. Rail travel and public transport must play a crucial role in this new paradigm as the backbone of an integrated shared mobility system. Rail and public transport are the most sustainable modes of transportation, for both urban and non-urban travel addressing crippling congestion, road safety and air quality.
