John,
Can you take the shell off your engine and tell me does it have QSI on it?
If so the QSI system for the Crown Edition diesel engines has engine sounds(engine revving goes up as more voltage is applied to the track, decreases accordingly too). To get the bell you must be near 8 volts or less, also the bell quits if you exceed a certain voltage but comes back on when you decrease to a certain voltage, the horn sounds as you have more voltage applied, must press horn or whistle control at higher speed to get the horn. Forgot to mention this, try using a low voltage to start out with as this triggers the announcement of "Leaving on track ten."
As far as I know there was no crew talk, crew talk is either Lionel or MTH feature, unless an owner had it upgraded, not a Williams factory option.
FYI; I knew a former independant Williams dealer back when it was Williams only.
I don't have a manual for Williams trains, usually it was provided with the engine when bought brand new, if it had one.
From my experiance with Williams they do best on an MTH Z-1000 transformer.
The new WBB has a new poly-morphic sound circuit, allows two sounds at one time if you have dual controls for bell and horn on your transformer.
