This is the first complete release of the mainline extension, including adjustment of the timetable for services on the mainline. More refinements are to come.

Mainline changes:
- Station 'Steenwijk' has been added to all services, including intercity services
- Station 'Meppel' has been added for all stopping (classed as semi-fast) services
- All times have been adjusted to deal with the single track part between Steenwijk and Wolvega, which limits the track capacity there to about 6 services per hour (until the long planned for second track was opened in 1975).

- All extra morning services are now run entirely by class 37's.
- Regular stopping services are done with class 127's
- There's a new slow coal run service from Meppel to Heerenveen. It needs to let faster traffic by twice.

There's a hard crash at 9:55 am, so reverting back to an older version.

Timetable update for the mainline. There's an issue/bug at 9:55 am.

Minor fixes.

First release of the Mainline Extension. The Scenery is 85% complete.

Timetables & refinements are to come with future updates, but there are 2 playable 'sneak peak' services for now. One down with class 112, one up with class 37.

Stations added / Line information:
- 'Peperga' station (no passenger services)
- 'Steenwijk' Station
- Remnants of a closed stop 'Nijeveen'
- The line joins another, busier mainline, just before station 'Meppel'
- Route ends just before 'Staphorst' (closed).

Meppel Station is quite large with 12+ tracks. Historically, some passenger trains would split and combine here - the service from Leeuwarden and the one from the other mainline would then travel onward combined. This is why there are platforms 2A and 2B, 3A and 3B with scissor crossings halfway the main platform.

Small change - simplified speed limits at Leeuwarden Station

Squeezed two new class 37 services on Leeuwarden-Stavoren line (back and forth train connecting to the ferry).
On return to Leeuwarden, you'll be greeted with 3-4 services heading out.

The Leeuwarden -Stavoren service now operates with class 117s.

Added extra scenic / empty stock moves using the new tracks at Leeuwarden.

Leeuwarden Station - added several tracks at the south end to make it very close to the actual 1965 layout.

Added PTT (Royal Mail) platform, railway works sheds. This makes the feel/flow of the track layout much better.

General Scenery update around Leeuwarden station.

Stavoren scenery update.
Speed into Stavoren station lowered from 35 to 25mph.
