Not quite 1934, but when I started at Brighton as a Secondman/Driver's Assistant in 1981 the diagrams (i.e. just the activities and start and end stations for each journey that constituted that 'turn') and any alterations were posted in a notice case. It was the driver's to match these with the Working Timetable (WTT) and 'Special Traffic Arrangements' (STA)and provide his own stopping pattern.
I can't remember when exactly, but towards the end of the 80's, possibly around the time I qualified as a driver in 1987, a diagram started to be provided for each diagram for the duration of the applicable timetable, supplied in a small plastic sleeve and held in a rack by the noticeboard until required. There was still no stopping pattern and driver's still had to use the WTT/STA to work this out and write it on the back of the diagram. It did mean that (subject to short term alterations) that the stopping pattern had to be worked out only once per timetable. On the first day of a new timetable there would be much to-ing and fro-ing from the locker room to retrieve WTTs for this purpose.
At some point, possibly after Connex took over, we were issued with a folder with all Schedule Cards for your home depot, by this point stopping patterns were included. Pages were colour coded to avoid confusion, Mon-Fri yellow, Sat green and Sun pink. The use of the folders fizzled out after a while, possibly due to increased computer and printer availability, and Schedule Cards with stopping patterns were printed out as required.
Attached are two photos, one of a Connex era amended Sunday diagram card, still in basically the same format as a 1981 diagram that would have been posted in the noticecase, with the addition of the length of turn. Pre flexible rostering in 1982 all turns were 8 hours in length (with rare exceptions agreed between Management and the LDC (Local Departmental Committee)).
The second an average Mon-Fri Schedule Card from the Connex folder of schedule cards.
