A Summary of Major Maintenance and Construction Projects

The vast majority of the work to improve railway lines, which impacts on the frequency and journey times info as per the journey guides, is completed over one Sat/Sun period.
So if you can't find a usual route or a train departure online, it can be worth having a look at the links to the national construction work, which you will find below.
You may then have to translate what you'll find, but it can be worth the effort to discover what's occurring and to glean whether you'll need to take a bus for part of the journey, or whether trains are being diverted.
Alterations to the usual service are often not particularly obvious when looking up the journey on a ticket booking service.

The information included below is a guide to the the more extensive construction projects which are impacting on train services for a week or more.
Therefore these are the projects which are good to be aware of if you're planning a rail pass itinerary and want to avoid any hassle, or are wondering why a typical connection isn't available on multiple dates.

Also worth knowing is that many major construction work projects, which require timetable alterations, aren't confirmed until around two months ahead.

These are the upcoming rail construction projects which;

• last more than a weekend, so also impact on Monday to Friday travel
• affect long-distance express trains
• result in trains being diverted, with longer journey times (which impacts on connections)
• Or, are being substituted by buses for part of the journey.
