Dublo Rail Reshaping and Bending
 

A friend of mine has asked if I can reshape a small 300mm section of Dublo railway line from a single curve to a "S" double curve to join two sets of points on his layout.
Not being a modeller myself I'm looking for advice regarding the feasibility of bending the length of Railway to a template without causing damage to the rails. Has anyone any experience of performing this type of reshaping and if so what are the chances of getting an accurate bend while maintaining the rail gauge.
