Two types of bogies were considered for the 117 series before a third was chosen.
The high-speed DT24 air spring bogies from the 153 series were considered but passed over, as were the DT21 coil spring trucks, standard at the time.
Ultimately, the 117 series was equipped with DT32E bogies on the powered cars and TR69H bogies on the trailers.
