Hmmm… There were so many variations, it seems like they changed *something* every year.
By 1958, the books became prettier again, with new covers, a route map once again striking a balance between geographical and schematic, showing the borders, some nice-looking, if doodle-like, drawings, and the return of the small route diagrams, but instead of accompanying the tables, they got their own pages, marking new sections.

1961 marked a return to photos between the tables, and perhaps a typography change (and a new map, they seemed to mess with it all the time, too)…
1962 marked a milestone - the adoption of a new triple-digit table numbering system (and, yes, yet another map).
Numbering zones where set up around mainlines mostly radiating out of Bucharest, maintaining the principle of starting with the line to Craiova and continuing clockwise, yielding:
100 Bucharest-Roșiori-Craiova-Timișoara-Arad
200 Teiuș-Alba Iulia-Deva-Arad
300 Bucharest-Brașov-Sighișoara-Teiuș-Cluj-Oradea-Episcopia Bihor
400 Brașov-Ciceu-Deda-Beclean-Dej-Baia Mare-Satu Mare
500 Bucharest-Buzău-Mărășești-Suceava-Vicșani
600 Mărășești-Tecuci-Bârlad-Iași-Ungheni h.
700 Bucharest-Urziceni-Fărei-Brăila-Galați
800 Bucharest-Constanța-Mangalia
These "magistrale" for the most part remain the same today (notably, 200 would be extended to Brașov via Sibiu in the late 60s and the 100 zone would be shortened to Timișoara (by the 70s) and renumbered to 900 in 1996), although the branch line numbering would be tweaked. A lot. Case in point - in 1962, the lines to Giurgiu were 801 and 802. Already in 1963, they were renumbered 101 and 102. But that map looks so much better, so that's what I'm going to show. I think they changed the fonts again, too, going all-in on serifs.
