Hello.
The letters are correct. The steam railway doesn’t serve these stations. I.o.w must be there somewhere. Why does the clue finish with - familiarly? Just cannot solve it.
Not sure if this helps but I suspect it will end with IWR which is the initials of the company that built the line originally (Isle of Wight Railway). Still can't figure out the first letter though.
I have just received the latest RAIL magazine. The answer to the clue is IOfWR. Sorry, I still cannot understand the answer. Their were winners- so they knew!
Thanks for your help.
