I have a Williams F7 ABA set of Pennsylvania engines that are before the TB-2 time frame. They have the sound in the B unit, "train departing on track 10, clear on track 10". Email me or get ahold of me on here if interested.
I have sold the Pennsy set of ABA F-7's. Have a set of ABA F-7's for the Santa Fe RR and six passenger cars, El Capitan set.
If the price is right, you have a deal!
