We believe that wellbeing, and a safe and supportive environment for both body and mind, is the foundation of a healthy workplace where our team can flourish.
Private health insurance
Supporting health, inside and out
We offer private health insurance to all our employees, providing access to a wide network of healthcare providers and wellness programs.
With this coverage, our team can focus on what matters most: staying healthy and energised, with their needs taken care of. It reflects our commitment to cultivating a workplace where the consideration of our team is always a top priority.
Mental Health at Work Commitment
A safe space to breathe
We recognise that mental wellbeing is as vital as physical health. With qualified Mental Health First Aiders on our team, we are here to listen, support, and guide.
We're committed to the Mind Mental Health at Work Commitment and take meaningful steps to create a culture where every individual feels seen and supported. From regular check-ins and mental health days to open conversations and educational resources, we are creating a workplace where our people can feel grounded and safe.
Social connection
Connecting together
We know that strong relationships and a sense of belonging contribute to both mental and physical health. That’s why we regularly bring the team together through social meetups, team lunches, family days and our annual Spring Summit hiking weekend – as a time to step away from the everyday, reconnect, and reflect as a group.
These moments of togetherness help strengthen bonds, spark collaboration, and create a supportive community where our team feels valued by each other.
Cities around the world are under growing pressure to manage complex transport systems, especially when faced with disruptions from extreme weather, technical failures, or large-scale events. Each incident can ripple across the rail network, causing cascading delays, passenger congestion, and communication challenges for operators and policymakers alike.
Building on our success as Global Grand Champions of the SAS Hackathon 2024, we wanted to continue pushing the boundaries of what’s possible with analytics and real-time data. We wanted to explore how analytics and real-time data could transform the way these challenges are managed. For our SAS Hackathon 2025 submission, our team developed a proof of concept for a Digital Twin of a regional rail network, built on SAS Viya.
What is the challenge?
Transport disruptions don’t happen in isolation. A single line closure, storm, or event can quickly affect multiple routes, impact passenger flows, and cause widespread knock-on effects. Yet, many transport networks lack the real-time systems needed to anticipate and model these impacts as they unfold.
Our challenge was to design a solution that could:
Simulate and forecast the impact of rail disruptions in real time
Enable operators to reroute services dynamically
Forecast passenger numbers during peak hours or events
Estimate financial and passenger impacts of delays and cancellations
Support faster, data-informed decision-making
Our solution: The Event Horizon Digital Twin for the rail network
Using SAS Viya, we built a Digital Twin that integrates live data streams with forecasting, optimisation, and intelligent decisioning models to replicate the behaviour of a rail network under stress.
This system can:
Predict disruptions caused by weather events, such as floods or storms, using live APIs and historical data
Model the cascading effects of delays or closures across the wider network
Suggest alternative routes or transport modes for passengers
Forecast passenger volumes during events or peak travel times
Automatically trigger alerts and rerouting workflows through Agentic AI
During the hackathon, we focused on one regional network to demonstrate how a framework like this could reveal where, when, and how disruptions matter most - not just for individual stations, but across the entire connected system.
How the Digital Twin works
Our approach brought together multiple SAS Viya components:
SAS Studio – Data preparation and processing
SAS Visual Analytics – Real-time dashboard and visualisation
Model Studio & Model Manager – Predictive and forecasting model development
Event Stream Processing – Integrating live API feeds (e.g. flood warnings)
Visual Forecasting – Predicting passenger numbers at peak times and during major events
Optimisation – Identifying the most efficient alternative routes
Intelligent Decisioning – Automating alert workflows and rerouting logic
For example, when a flood warning API triggers an alert, the system immediately identifies the high-risk area, recalculates the most efficient routes using optimisation models, forecasts the impact on passengers, and automatically generates alerts to operators and customers.
All this information is displayed through a single Visual Analytics dashboard that updates as new data arrives, providing a unified, command-and-control view for transport planners and decision-makers.
The expected impact
By combining real-time data with predictive modelling and automation, our Digital Twin demonstrates how cities can move from reactive crisis management to proactive, data-driven transport planning.
Potential outcomes include:
Reduced disruption impact through faster decision-making and automated rerouting
Improved passenger experience with timely alerts and alternative travel options
Stronger operational resilience for transport operators and emergency services
Data-backed infrastructure investment decisions for policymakers
Ultimately, our goal is to help cities become more resilient, connected, and sustainable, ensuring public transport continues to run smoothly, even when disruption strikes.
About the SAS Hackathon
The SAS Hackathon brings together teams from around the world to collaborate on data-driven solutions that tackle real-world problems. Using SAS Viya’s powerful analytics, machine learning, and AI capabilities, participants design and prototype solutions across industries.
We are proud to have contributed an innovative approach to improving transport resilience and look forward to exploring how this concept could evolve into real-world applications for public infrastructure and mobility planning, and look forward to SAS announcing this year's winners in December.
We’re proud to announce that Sara Boltman, co-founder of Butterfly Data, has recently joined the DAMA UK Committee. This is a great milestone that reflects both her individual expertise and Butterfly Data’s deep commitment to data management excellence.
About DAMA UK
DAMA UK is the UK chapter of the Data Management Association International (DAMA International), a not-for-profit organisation dedicated to advancing the understanding, development, and practice of data management.
