MAP24

MAPNA 3300 HP Freight Locomotive (MAP24) has been designed and executed to produce a kind of freight locomotive at MLC to meet railway transportation requirements. It was designed and manufactured to be fully compatible with the worst environmental conditions, especially for IRAN’s climate.

MAP24 was equipped with a turbocharged 16-cylinders diesel engine, 3300 HP nominal power, therefore it is considered a diesel-electric locomotive. The driver’s desk was designed and manufactured based on the best ergonomic conditions to provide much more facilities and comfortability for locomotive’s driver.
Using the thermal and acoustic insulations in the cabin’s roof as well as the installation of air conditioning systems (HVAC) with adjusting temperature are some of the special features of the MAP24. Due to using advanced and up-to-date equipment in the control system of this locomotive, the troubleshooting process, service, and maintenance were improved significantly, in addition, the reliability increased too. Brake system enhancement by utilizing BFC cylinder and park brake has led to better safety, compared to similar locomotive. Design and manufacturing of the fabricated 3-axle bogie instead of casting bogie provides to use of a modified and proven brake system.
MAP24 locomotive is capable of being operated with one to three units (MU), to increase tractive effort.
