Digital Train Software

DigitalTrains is a sophisticated online suite of programs aimed at train operators and designers.
DigitalTrains can be used to design a trains crash energy management system, understand the trains performance under normal train operating conditions and how the train interfaces with rail infrastructure, such as buffer stops.

ROLLING STOCK DIGITAL TWIN TECHNOLOGY

DVRS has developed DigitalTrains, www.digitaltrains.online, incorporating Oleo International’s suite of rolling stock crash simulation software.
Continuing over 35 years’ experience of simulating train collisions and service conditions.
DigitalTrains brings together digital twins of individual elements, incorporating dynamic simulations that correlate with test results, enabling you to assemble a digital twin of the train and its key track infrastructure.
This is cloud based software that enables simulations to be completed very fast, usually in seconds, many iterations can be evaluated quickly and efficiently. The Digital Twins and simulation results are easily shared with others, making this an efficient collaboration tool for project managers, train operators and manufacturers to visualise, understand and optimise performance and cost.
Digital Twins of passenger and freight rail projects, including trams, light rail vehicles, metro, monorail, main line and high speed trains as well as freight wagons and locomotives.

DigitalTrains vehicle and track modelling is correlated with Vampire® and therefore should give good agreement with other Multi Body Dynamics software such as Simpack®, Nucars® and Adams®.

Simulation capability includes

  • Route and track profiles.
  • Static and dynamic gauging.
  • Track Quality Evaluation.
  • Dynamic simulations with Rail to Wheel contact.
  • Buffer Stop and Train Crash.
  • Derailment and Crash investigations.
  • Reliability and energy consumption.

Train running

Simulate train performance

“Train running” is a term DigitalTrains have adopted to cover any non-impact train operation. DigitalTrains can simulate the train’s performance under braking and tractive events on a defined rail track geometry termed as a ‘Route Profile’. Route profiles are user defined and may consists of both vertical and horizontal geometry.

DigitalTrains has tools to create different braking and tractive characteristics against train velocity, distance travel, time or location on a route. For example, DigitalTrains can calculate side buffer forces around curves or coupler forces due to braking, the results can be shown graphically or shown as an animation revealing the interaction at an interface between physical features such as gangways.

Crash Energy Management

Assess & Design

DigitalTrains is designed to guide train manufacturers and operators to assess or design the crash energy management of trains both quickly and accurately. Use tools designed to recommend or optimise the solution.

Choose from a library of pre-existing solutions or create from a library of energy absorbing devices. Alternatively create a bespoke device using the integrated tools or uploading a csv file containing test or simulated data.

Buffer stops

Simulate performance

Buffer stops are a critical part of any rail infrastructure. These are essential safety devices used in stations and maintenance depots. Their performance is dependent the train’s crash energy management system and the buffer stop’s energy absorbing characteristics.

DigitalTrains can simulate the performance whether the buffer stop is a fixed stop, or a sliding friction stop. Either can be equipped with hydraulic buffers or rubber absorbers. DigitalTrains can recommend the sliding force or distance required for sliding stops or optimise the performance of hydraulic stops.
