The NS Class 186 is a type of B-B electric locomotive built by Bombardier Transportation between 2006 and 2014.

These locomotives were intended to be a temporary measure until the V250 high-speed sets entered service.

The leased locomotives were delivered in a red livery with white fronts, but since 2015 are being repainted yellow-blue.

Sale to Akiem Since NS plans to replace the push-pulls sets with high speed multiple units in the near future, the old coaching stock will be withdrawn while these comparatively new locomotives will be useless.

In 2018, NS took a sale-and-leaseback agreement with Akiem for the entire Class 186 engines they own.

The NS Class 186 fleet comprises 45 yellow/blue locomotives leased from Akiem and 18 from Alpha Trains.
