childrens book about people from roadsigns who operate a miniature railway

[34D]

I'm trying to recall the name of a book (a series, I think) that I read in my childhood (1980s).

The people from roadsigns came alive at night, and among other things, operated a miniature railway.

Any ideas, anyone?

Is it Roddy the Roadman by Phyllis Arkle?
