I have not heard the Crew Talk version of the older Williams engines. Does it have the QSI sound board?
The one that has the announcement "leaving on track ten" is a start-up only feature, and will only work at low start-up voltage. It has the QSI sound board. This is part of an F-7 ABA set of three diesels that I have, the unpowered B unit has the QSI sound circuit board inside and center rail pick-up rollers. These are from the Crown Edition era that I have.
