Like its sister, the TW120 Sleeper, the TW120 LIGHT is a flat bottomed reinforced concreted twin block sleeper used for embedded rail slab construction.

The unique profile allows for shallow depth slab track installation and the integrated features help generate significant cost and time savings, on both the track construction and programme, as they facilitate quick installation, reduce maintenance time and enhance track quality.

Around 20,000 Sateba TW120 Sleepers have been supplied to the Midland Metro line in the UK, and are a common sleeper type for light rail construction throughout Europe.
