In the 1950's there was a comic called the Eagle, In this comic the centre pages always had cutaway drawing showing how things worked.
They covered trains, cars, planes cars along with other subjects.
Here I have put together my collection of the railway cutaways found in the comic, I do not have the full collection so if anyone has any I'm missing could you please let me know
I am planning to eventually add the drawing from the other categories from this page so this is still a work in progress
