As part of its strategic supplier partnership with Alstom, BFG International produced fully integrated toilet cabins for these trains. The toilet systems comprise internal polyethylene waste water tanks, a 2-litre greywater system, and EVAC vacuum toilet system. A contact moulding process was used to produce the parts, with a gel-coated finish for internal surfaces and painted finish for external surfaces. All parts comply with DIN 5510-2 fire safety regulations.
