I have been building model railway trackwork and semaphore signals professionally for over 25 years and have now expanded into offering bespoke colour light signals as well.
I have also designed various etched parts for model railways, which have been produced in either brass or nickel silver. Now I am beginning to embrace the 3D printed world as well, mainly for signalling parts but also some track parts hopefully. More news on this in due course.
Below are some Youtube videos of the more interesting projects of recent times along with with some still images.
