The **CFL class 4000** is a variant of the [Bombardier](/source/Bombardier_Transportation) [TRAXX](/source/TRAXX) locos found working across Europe. Within [Luxembourg](/source/Luxembourg) they work on the local passenger services, crossing the borders into France or [Belgium](/source/Belgium) as necessary. They also work freight traffic. Their 15 kV capability allows them to work across the border to [Germany](/source/Germany). Even though they are capable of running in [France](/source/France), they are not allowed to do so for security reasons.[clarification needed]

Their slab sided body work has been used for advertising.

Along with the [Bombardier bilevel cars](/source/Bombardier_Double-deck_Coach) that they pull, the Class 4000 are due to be replaced by [electric multiple units](/source/Electric_multiple_unit) by 2030.[1]
