Missed last week's competition, but I note that the answer to question 1 was William Madocks.
I presume the question setter has some connection with this area as Madocks was the MP for Boston. He was responsible for the building of the Festiniog Railway which terminated at Port Madock, named after Madocks. Recent Welsh inaccuracy has changed the name to Portmadog. I believe that he was also involved in the Welsh Highland Railway (answer to question 2). The Festiniog Railway works is called Boston Lodge.
