You must study your entire route in surveyor, and place your own special notations of importance, on various signs, ie:
C+ SO Note (Scenery) White Nameable - by: itareus <KUID:243828:1945>
Instruction sign, 12 lines scripted - Willem2 - <KUID2:97008:29100:1>
ie: "Junction Zoo Interlocking-1 mile", or "SLOW DOWN-RED SIGNAL AHEAD"
There are many nameable milepost signs, and you can write them down in a Marble Notebook
A real engineer, and conductor, are trained by an elder engineer or foreman, and are taken for a instruction trip down entire the rail line, receiving verbal instructions from their elder experienced instructor, teacher. Only when they know the entire line by heart, and can predict each and every next location, milepost, industry spur, station, or signal, then and only then, are they officially "Certified" by the instructor or road foreman, to be able to drive on their own, down the line, from terminus to terminus.
