I was a bit concerned to be notified of 'bauarbeiten' affecting services into Germany from Belgium from early last week as I was about to travel that way. However, the replacement is an hourly shuttle between Welkenraedt and Aachen which connects with the Brussels-Eupen service and reverse, meaning that you can now travel from Brussels into Germany hourly, and more quickly, than the usual two hourly. Having been frustrated a couple of times by inconvenient times and waits in the past this was actually quite welcome. This continues until mid-December.
