The thing that stood out to me the most in these was the route map, which leaned very heavily into schematicity, more so than any equivalent I can think of. The whole design unsurprisingly rests upon a central element - the line going north from Bucharest and making a nice curved triangle shape in Ploiești. Everything is cheerfully distorted in order to give the Bucharest-Brașov-Sighișoara-Teluș-Cluj-Oradea-Episcopia Bihor a nice striking straight diagonal stroke. The line to Craiova and Timișoara might even look kinda fitting to you until you realize it still ran via Pitești at the time. The Danube, Black Sea and Dniester are shown as ship routes with thick dots. Otherwise, dashed lines are narrow-gauge, small dotted lines are private railways. I assume the double lines were, well, literally double track.
As for the table numbering, CFR went with a rough ordering starting once more from the Bucharest-Pitești-Craiova-Timișoara line as number 1, but this time continuing in a circle, branches inside to outside, then clockwise, such that the mainline though Brașov and Sighișoara got numbers 29 (to Arad) and 30 (to Cluj and Oradea) and the last 'mainline' table, 131, went to Giurgiu-Videle.
