Engine Performance Data Rated power of 0KTZ85M-00-00
Track gauge – 1000 mm. Standard meter-gauge width, enabling operation on 1000 mm narrow-gauge
railways.
Axle load – 21 t per axle. Defines the bogie's maximum static and dynamic loading capacity for
robust service.
Wheel diameter – 840 mm (new). Balances ride comfort, low floor height and track clearance on
narrow-gauge lines.
Free height of center plate – 710 mm. Sets the vertical connection interface between the bogie and
the carbody.
Minimum curve radius – 145 m. Capable of negotiating tight curves, ideal for sharply curved and
mountainous routes.
General assembly drawing No. – TKZ85M-00-00. Reference number for the bogie's complete assembly
drawings.
In summary: This meter-gauge bogie (TKZ85M-00-00) is designed for 1000 mm gauge track, rated at 21 t axle load, with 840 mm wheels and a 710 mm center plate free height. It can traverse
curves down to 145 m, making it well suited for narrow-gauge passenger and freight service on sharply
curved lines.
