Mk1 (Class 594) and Mk2 (Class 598) DMUs "TRD" (Tren Regional Diesel) of RENFE-Regionales, seen at Sevilla-San Jeronimo.
Apart the end-faces, one can also spot differences in liveries and logos.
Both units are fitted with the SIBI tilting-system of CAF, as of construction (Class 598) and under a subsequent upgrade in 2001/2002 (Class 594).
