Frequently asked questions about Föli’s new trunk line network

The new trunk line network’s improved transverse connections and shorter intervals between departures will make transferring buses much easier and even eliminate the need to check timetables.

Turku Region Public Transport Föli’s new bus route network, called the trunk line network, will be implemented in 2021. The renewal aims at improving ease of travel, creating better transverse connections and shortening intervals between departures. At the same time, the line network will be streamlined and the hierarchy between lines clarified. This page collects the most frequently asked questions about the new trunk line network.

What is the trunk line network?

Föli’s new bus network, which is scheduled to be implemented on 1 July 2021. The actual implementation date is, however, dependent on the completion of the construction works around the Market Square. The line network map can be viewed at

Why is the renewal being carried out?

The renewal aims to improve the ease of travel by increasing transverse connections, improving the accessibility of the entire Föli region and reducing the intervals between buses. For example, transverse connections are currently largely dependent on line 99, which only has two departures per hour on weekdays and none on public holidays. Conversely, the new circular trunk line will have intervals as short as 7–8 minutes during peak hours and 10 minutes on public holidays.

What is a trunk line?

A trunk line is a bus line with short intervals between departures, primarily 5–10 minutes, and a route that is intended to be streamlined and follow major roads. There are a total of 10 trunk lines, with one being a circular line and the rest running via the city centre.

In addition to the trunk lines, the new network includes feeder lines (short intervals and connections along the trunk lines), complementary lines (lines with longer intervals, similar to current ones), service lines and school lines.

Why is my route being changed?

The routes of the trunk lines are intended to be streamlined in order to make journeys faster. This is why the distance to the closest bus stop may increase in some areas as a result of routes being streamlined compared to current ones.

The trunk lines will run via the city centre between two areas (such as Uittamo–Härkämäki). The aim in the choice of termini is to achieve a balance, with departure intervals that are ideal for both areas. The choices have also been influenced by residents’ wishes, the growth potential of different areas and the cost efficiency of the solutions.

Why is my direct connection being changed to a transfer connection?

Direct connections cannot be offered from every area to every other area, as doing so would be prohibitively expensive.

At present, transferring to another bus requires thorough examination of timetables, especially outside of Turku city centre. However, the new trunk line network’s improved transverse connections and shorter intervals between departures will make transferring buses much easier and even eliminate the need to check timetables.

Will bus stops be removed?

Some will, as the target distance between the trunk lines’ bus stops is approximately 400 metres. Most people are prepared to walk a longer distance to a bus stop as long as the intervals between buses are short. Reducing the number of stops also speeds up journeys – even with the same number of passengers, the time taken up by the bus having to brake, accelerate and open its doors is reduced.

(You can view the bus stops to be used from 2021 onwards on the online map of the trunk line network page by clicking on individual lines.)

What about older people and those with bad legs?

It is true that journeys that require you to transfer between buses and longer walks to bus stops are not ideal for everyone. In recognition of this, the new trunk line network also includes new service line routes (lines V1–V6 on the map). The aim is to also keep the walking distances between transfer stops short and make the stops themselves accessible and more informative to passengers.

Will line numbers be changed?

Some of them will, though the current line names are only placeholders. The final line numbers will be decided at a later date.

Who decided on the implementation of the new trunk line network?

The City of Turku made the decision to implement the trunk bus system back in 2009. In 2016, it was decided that the renewal would be based on trunk lines running via the city centre and a circular trunk line outside of the city centre, and that the complementary line network would be increasingly based on transfer connections.

The Turku City Region’s Public Transport Committee decided on the routes of the trunk line network on 23 January 2019, and the Turku City Board decided on the funding for the network on 4 March 2019. At the same time, it was also confirmed that the new trunk line network would be implemented in summer 2021.

Were passengers consulted on the matter?

The thoughts of passengers on factors that limit the use of buses were surveyed in 2016, before route planning was commenced. The number of replies received was 1,700.

The first drafts of the trunk line network’s routes were published in summer 2018. Comments about the drafts were requested from a number of different parties, such as the Föli municipalities’ various committees, local associations and the public. The number of official statements received was 38, in addition to which approximately 1,000 comments were received from the public. The drafts were also presented at public events. The line network was adjusted based on the received feedback before it was submitted for decision-making.

Where can I find out more about the new line network?

On Föli’s website at Public events about the renewal will be organised closer to the actual implementation date.
