One of the consultation paths as part of the Horizontal Timetable project are consultations with 18 public transport authorities – all 16 regional governments (self-governments of voivodships), as well as the Warsaw City Transport Authority (Zarząd Transportu Miejskiego w Warszawie) and the Upper Silesian-Dąbrowa Basin Metropolis (Górnośląsko-Zagłębiowska Metropolia). These are the largest organisers of public rail transport, after the minister responsible for transport. Consultations with this group of project stakeholders include:

• identifying their needs and expectations regarding transport services within the system of interregional and international rail connections (taking into account both regular services and seasonal trains),
• accordance of transport service proposals from key transport authorities in order to develop solutions enabling the coordination of their timetables (taking into account regional express services, including those on planned high-speed rail lines),
• discussion of the concept of rail and bus feeder routes providing access to long-distance rail services from every county with a maximum of one change,
• discussion of the feasibility of integrating fares and timetables for regional and long-distance services on selected routes,
• identification of investment needs on the Polish rail network resulting from the planned transport services.

The aim of this path of the consultation process is to develop a coherent country-wide transport offer integrating long-distance, regional and metropolitan rail connections, and thereby to begin planning timetables and the development of rail passenger transport in Poland in the long term.

Invitations to participate in the consultations were sent to the stakeholders on 16 July 2024. Between 15 April and 2 October 2025, a total of 16 workshop meetings were held in all regional capitals, including combined workshops in Warsaw and Katowice – in addition to representatives of the self-governments of Mazovian and Silesian voivodships, representatives of the Warsaw Public Transport Authority and the Upper Silesian-Dąbrowa Basin Metropolis were also present. The workshop meetings were preceded by a phase during which stakeholders could submit their comments on the proposed long-distance transport services.

A total of 157 experts took part in the workshops with regional and metropolitan rail transport organisers, representing both the above-mentioned self-government institutions and the Ministry of Infrastructure, the Central Transport Hub, PKP Polskie Linie Kolejowe and the Centre for EU Transport Projects. Local government stakeholders submitted a total of 727 comments, proposals and requests, including 303 relating to regional transport services, 219 concerning long-distance connections and 205 regarding railway infrastructure.
