Class 56501 'Kreigsloks' 56513 and 56530 combined to work the 07:05 Afyon - Alasehir mixed up the bank west of Aksuzkoy, between Banaz and Usak, on 11 April 1984. Early locos were equipped with 4-axle rigid wheelbase 'Steifrahmen', literally stiff frame, tenders, as can be seen behind the leading loco, before the more familiar 'Wannen' tub tenders were introduced.
