Part task simulators are an economical version of static cab simulators and contain the driver desk with full instrumentation along with the driver chair. The desk simulator may be fit with a 3 DOF motion platform to provide sensory immersion in a sensory immersive environment.

In this simulator, the driver desk along with the visual and sound systems are placed within a mobile vehicle—a small car, van, or large transport container, depending on the requirement. Mobile simulators take the training center to the driver’s location. They have an air-conditioned environment and can be placed in any parking lot to provide training. They will typically contain the driver desk with replica components.

Special purpose simulators may be designed for special applications such as accident relief, traffic management, disaster management, signaling systems, station operations, yard operations, or any similar purposes. They may also be designed for other vehicles such as cranes.

This provides an opportunity for the trainee to be fully immersed in a real cab environment. The cab contains a near-realistic interior with accurate ergonomics as per the original cab. The cab will be fitted with a front visual system and, optionally, with side and rear view system. It will come complete with all radio communication systems, passenger communication systems and an instructor communication system. All cab instruments are suitably modified for low-voltage operation in a safe, simulated environment.

The visual simulator system consists of computer generated images (CGI) which may be displayed on an LCD screen or projected on a camera. The visual simulator will be able to simulate  weather conditions such as rain, fog, heat and the different times of day. An instructor will be able to change visual elements like the signals, add obstructions on the track, control the traffic on the track and change the loading in the vehicle. 

C.C engineers has developed the SOVAC technology which provides photo-realistic high resolution imagery. It is accompanied by a sophisticated and detailed state-of-the-art sound system that simulates various sounds a driver might encounter on a train--fault sounds, machinery, people on the platform, etc.

Every simulator is governed by mathematical models for simulating the dynamics of the train. The math modelling takes into consideration the composition of the train, the loading, the tractive power (traction),the break power applied to the selected track, the curvature and gradient of the track, the track condition (slippery/dry) and the super-elevation. The train modelling also includes the modelling of all possible malfunctions and troubleshooting of the same.

The instructor console will be equipped with a number of monitors to monitor and control functions of the simulators in an interactive training environment. The console shall have graphical representation of all train components which will help the instructor interact with trainer and guide him during training sessions.

The observer station consists of large monitors that indicate the driver’s actions taken inside the cab. It has provisions for marker keys which can be operated by observing trainees.

The driver’s auxillary display an additional monitor which is provided inside the driver’s cabin. This monitor gives indication of the trend position on the selected track and graphical data for track gradient, curvature, and corresponding coupler forces and other dynamic simulation results that are used for controlling the train. 

Driver’s actions on specific terrains are largely dependent on the type of load, percentage loading and the condition of the wheels. The simulator permits formation of rakes with differing loads. Multiple locomotives may be connected in a train consist at any desired location in the consist.

The motion control for simulating a realistic feel in terms of roll, pitch, heave, search, sway, and yaw actions of the locomotive are recreated by the motion platform, through a software computation model. The motion platform also generates motion for discrete track discontinuities and for jerks relating to cutting off of traction motors.
