IST Simulations is delighted to launch a new product: Modular Simulator.

The Modular Simulator is a simulator of an NX panel where the infrastructure displayed on the panel can be configured by the assessor to enable focus on the infrastructure relevant to the session, and reduce distraction from infrastructure that the signaller does not need to learn.

Eg. If the signaller being trained does not have a CCTV level crossing, then the CCTV crossing can be removed from the layout. If the signaller being trained has axle counters, then the axle counter controls can be displayed.

This flexibility enables the Modular Simulator to be used from the most basic of training on a new signaller’s very first day, through Initial Signaller Training, training of rules, reviewing of incidents/errors, right through to continuous professional development of experienced signallers, and much more.

IST Simulators have Product Acceptance for use in Network Rail locations.

If the video does not display above you can watch it on YouTube.

The items shown in black are the ‘base’ level and always present. So with all Modules switched off, the panel is a simple ‘up and down’ line and two platform loops: Perfect for early-days training.
