Which field do you mean, the timing load and operating characteristics?

I believe the date field below them is coded as follows: (days)O means running only on those days, (days)X means running on all days except those mentioned. T is Tuesday and Th is Thursday.

All of the codes are explained in book CY00.

It would help if you gave specific examples (with a page and column reference) of what you're struggling with. Give details. As already mentioned, book CY00 details codes and acronyms used.

The WTT tells you. One is marked as MO (Mondays only) and the other is marked as MSX (Mondays and Saturdays Excepted). The same train carrying the same goods but timed differently on Monday to the other days of the week,

To throw in a few more examples:

Columns 53/54/55
One path through the area with 3 possible trains running in it.
Hence noted 'Q' and 'Y' as running to or from different places, or not at all.

Columns 63 to 68
One path through the area with 6 possible trains running in it.
For this it is clearer that there are 3 origins and two destinations and all combinations covered, so again noted 'Q' and 'Y'.
For the purposes of a Marylebone sim, as only one can ever run you might choose to only put one in the timetable, rather than all 6 and then choose one. If you expect to do an adjoining timetable and promote it as being chainable, perhaps all 6 are worthwhile (eg Oxford as some originate Hinksey Yard)

Columns 68 and 69
Two different timings for essentially the same Southampton - Crewe train. The difference is note Z (can carry outsize loads) which requires the train to run via the alternative (Coventry) route.
For this you probably would put both in with a decision as to which runs if the variations are in the sim area.

For setting up the sim train type you need to extract the maximum speed and some rough weight data from the timing load.
It is also sensible to get a reasonable guess at length from it.

Speed is given explicitly.
Weight is only given as a maximum in 100's of ton. You have to translate this, and the embedded loco class information, into the SimSig 'acceleration' and 'weight' selections.
That is far from an exact science !
It helps to get an idea of what the trains are, so going back to column 64 (6M27 Hinksey - Stud Farm, timing load 60-66S06) this looks like an empty ballast train as it is only 600T.
Not much for the indicated single 66 so acceleration might be 'standard'.
The incoming is a different matter, in column 123 it is 1800T so likely 'heavy&slow'
The 600T also gives you a length based on the typical wagon weight when empty.
