Dinner at the Roundhouse Thursday 16th October 2025 Derby Arena, Royal Way, Derby, DE24 8JB 

The Rail Industry's favourite networking evening was another huge success in 2024. What will 2025's dinner bring? 
Mainspring's 'Dinner at the Roundhouse' is a chance for the biggest names in the rail industry to gather together and celebrate the last twelve months, forge new connections and look forward to the future within the spacious Derby Arena. 
 
Celebrating collaboration and innovation, Dinner at the Roundhouse brings together operators, manufacturers, constructors, consultants and partners from across the supply chain with national and local politicians to discuss the opportunities that the future can bring.  
 
Make sure that, like around 800 other Rail Professionals, you ensure your place at the very heart of the action within the very heart of the Railways in 2025. 
“The Dinner at the Roundhouse continues to be the Derby rail event of the year. The mixture of networking, speeches and music provides an unrivalled evening which is always one of the first dates in the diary.” 
 
Stefan Rose, Chief Investment Officer at Porterbrook
