Luxembourg's railways, the CFL, has announced that lines 10, 50, 70 and 60/90 will be temporarily closed at various times during August and September. 

The temporary closures are to allow maintenance, modernisation and extension of the rail network throughout the Grand Duchy. To reduce the impact on passenger, the CFL organises such works to take place during periods when passenger numbers are traditionally lower, such as school holidays, week-ends and even at night.
