a) I am located near Ruislip. I am narrow gauge. I have 3 stations. 1 of my stations is only open for special events. I have several diesel trains but only one is steam. My first train was steam operated and was called Mad Bess.
b) I am served by 50 stations. 36 of my stations are underground. I had a project to expand me out to Bushey Heath but that project was abandoned. I am the busiest line on the London Underground network.
c) I opened in 1961. I am exclusively served by 1967TS. I get new trains this year. I was the first line to have automatic ticket machines instead of passengers having to buy tickets at a ticket office. I have more obvious clues than any other network Reddog785 has listed.
