Youngsters from Brooklands Farm Primary School visited the headquarters of Network Rail last week, to show what they had learnt during Science and Engineering Week.
The school had partnered with Network Rail, which is responsible for rail infrastructure throughout the UK, for a week of activities last month.
Pupils took part in a range of activities supported by staff from Network Rail, such as making a railway bridge, re-routing a train in a mock control room, designing posters about rail safety, and writing stories and poems about train journeys.
There were also trips out of school to the Signal Control Centre in Rugby and to the Northampton and Lampton heritage railway line.
At the end of the project, children from every year group visited Network Rail, where they gave presentations to the staff about what they had learnt.
Headteacher Maxine Low said: “We have been overwhelmed by how the children took such an interest in this project. The engagement from Network Rail staff was fantastic.
“During the week and at the presentation, the staff and the children questioned each other about the experience and helped to develop deeper thinking.”
