1 März 2023 - Vallentuna, Markims Örsta. Midbus runs line 662Y through Markims Örsta. The former line 662 has been shortened and no longer enters minor roads. Later, the new line 662Y (Y for Yvlinge, a stop on the road) was started, which runs once in the morning and once in the afternoon on the former line stretch. Midbus runs it until Transdev can take over the line.
