In 2003, the previous CSV-DP government decided to build an underground train station at Findel.

In September 2008, the first excavator made its way to Findel. A year later, the new CSV-LSAP government opted to end the project due to its cost.

Since then, a long unused tunnel exists under the lux-Airport's multi-story car park. Equipped with cameras, RTL.lu decided to pay a visit.
