At Core4 we know that working quickly and safely on rail projects is paramount and we recognise that undertaking projects out of hours to minimize disruption to commuters and rail operators is of great importance.

We undertake platform extensions and sub-station extensions; including groundworks, troughing, signal bases, building and refurbishments, as well as underground works. We also have the skills and experience to be able to rise to the various challenges that a rail project can present. 

We offer a range of services including the surfacing of station platforms, car parks, pedestrian footpaths, and access roads.

Our Core4 Values

We are a growing company, always constructively pushing ahead. Our staff and supply chain are the key components to ensuring that we deliver for our clients.

Professional Service

Customer service is our number one priority. Your experience matters to us. Which is why we are committed to upholding the visions and values of the company and always provide you with the best service possible.


We are all aware that we need to do our bit for the environment. At Core4, we recognise that we are the generation that needs to make the changes to protect our planet. To us, the environment is more than just a policy.


We employ NEBOSH and IOSH employees as active members of staff and use an external health and safety consultant to ensure we are always getting the best and most current safety advice possible.
