Scheidt & Bachmann System Technik, together with its partner Trans-SYS Kft, have developed the BEST operations and interlocking simulation system in order to meet the increasingly stringent training requirements on a long-term basis. With its realistic simulations, BEST is also used for planning line sections and interlockings as well as the specification of new systems.

For some 30 years, BEST has been deployed with great success by a great many European railway and metro operators. Every year, more than 10,000 train controllers take part in training courses on the simulator. BEST accurately reproduces the user interface of the original systems, including all the necessary operating menus. The simulation of the interlocking technology with all its external installations and train movements provides users with a highly realistic impression.

The system simulates a range of different interlocking technologies (mechanical, relay, electronic) made by a variety of manufacturers. In addition, existing simulations can be extended to include new technologies and individually adapted as needed. For example, BEST can be used to simulate both the existing interlocking technology and the new, control and operating systems.

The BEST training system:

• Training periods are shorter and can be more flexibly planned
• Improves staff confidence in daily handling
• Hazard-free malfunction and stress training
• Trains realistic scenarios (including timetables and disruptions)
• System is independent of manufacturer and type of interlocking
• Can be deployed as a multi-user system, a web-based single-user system, and as a learning platform for unassisted training
• Training for new installations is separate from commissioning
• PC components are independent of the original system

Beginning training earlier

The training system for interlockings is based on the same platform as the planning system. This means that data prepared during the planning process can also be used for training purposes. Therefore, no additional work or expenditure are needed to create training software. With the BEST simulator, training for a new interlocking can begin in good time, prior to commissioning.

Single-user simulators are also being increasingly deployed as a training method so that trainees can engage in further training through self-learning or prepare for important training programmes. Trainees operate these simulators themselves and work on specifically prepared practice scenarios.

BEST can also be integrated in the training as a learning platform and training content can be prepared for the learners on this basis. Practical tasks for various types of interlocking can be created for immediate application of the content taught and stored together with sample solutions.

The learning platform can be accessed from any location using a PC or a tablet, giving learners the opportunity to work on tasks individually and expand their knowledge independently. Separate software solutions for different applications are not necessary, as BEST fulfils the entire range of requirements – from stationary simulation systems to web-based training.

Simulation of interlocking logic and external installations:

• Real topography
• Manufacturer-specific differences taken into account
• Simulation of time behaviour in real time

Simulation of train and shunting movements:

• Rail operations according to timetable
• Interfaces to external timetable systems
• Manual setting of any train and shunting movements

Simulation of technical and operational failures:

• Adjustment of failures at all key external installations
• Realistic impact on operations
• Delays, re-routing, train disruptions

Multi-user simulation:

• Interaction of multiple interlockings, even of varying technologies
• Training of dispatching and safety-relevant actions extending beyond interlocking

Analysis of the simulation:

• Analysis of delay minutes in timetable operations
• Documentation of operating actions and non-compliance with regulations
