Two Railpool locos, 187.004 and an unidentified Class 186 negotiated the Wattinger Curve below Wassen with a southbound BLS Cargo intermodal on 8 August 2016.
The Railpool / BLS 186s were particularly hard to identify as they had black numbers cunningly camouflaged on a black and white patterned background. Once you had worked out where the number was and which of the 12 digits you needed, the loco was already too far away to read them. The numbers don’t show up well on photos either.
