Modula BDDTechnical Data

Hybrid locomotive for hauling freight

The Modula is a hybrid locomotive concept with different traction modules on a standardised centre-cab locomotive platform. These systems have the same interfaces so that, for example, the two diesel engine unit can be replaced by a two battery unit.

Variants:

This modularity allows the operator to adapt the locomotive quickly and easily to changing requirements. It offers a range of standardised functions and systems that can be assembled into customised versions to suit the customer’s specific requirements. With its high proportion of identical parts, the platform concept provides synergy effects and simplifies the management of replacement parts.

The Modula combines the characteristics of a main-line locomotive with those of a classical shunting locomotive, and the focus here is on flexible power sources. The customer’s application profile can be used to combine two power sources to make a single variant.

The control system in the Modula is designed with the future in mind; it can be upgraded with new functionality even years after delivery. It can also be equipped with a digital automatic coupling, a camera to identify obstacles or Augmented Reality applications for servicing. And if the locomotive’s intended use changes in the future, modifications can also be carried out accordingly.

The Modula-BDD variant is centered around two diesel engines supplemented by a small battery, providing a balance between conventional diesel power and limited energy storage for light traction purposes.

While the BDD is designed primarily for non-electrified areas, the small battery allows for energy-efficient operation in low-power scenarios, such as shunting or low-speed movements.

Its sturdy construction, excellent shunting performance, and the ability to maintain power across varied terrains make it a versatile option for operators that prioritise diesel power with supplementary energy efficiency.

  • Sturdy, mid-cab construction, excellent shunting locomotive qualities and a wide range of operational applications
  • Optimised vehicle design that takes into account the full range of customer requirements
  • Simple and flexible integration of current and future energy storage and electricity generation technologies (also hydrogen-based systems)
  • The EDD and EBB variants (draw power from the overhead catenary system) have considerable potential for savings in maintenance and energy costs
  • High level of reliability through the use of high-quality components
  • High availability thanks to a redundant drive configuration and two drive systems
  • Remote Cloud access to data and the locomotive’s condition enables its deployments to be precision-planned (an advantage when refueling or when replacing parts subject to regular wear and tear)
  • TSI approval in DE, AT and NL allows the locomotive an extension of approval in many European countries

There’s a focus on maintenance. Every Modula variant is designed for easy maintenance. The continuous analysis of sensor data allows maintenance work to be predicted and planned better, which means that downtime can be reduced considerably. What’s more, the modular system also allows the user to completely remove a diesel engine or battery unit, replace it with one that has already been serviced and go straight back into operation. This opens up completely new possibilities in the area of maintenance and service.
