You can add realistic sounds to older Williams locomotives with these separate-sale True Blast® Plus Sound Systems, which are now in stock.

Are the GP30 and the RS3 using the same sounds? They are both listed under the same numbers in the last post.
Just a typo - it is fixed.
So what about a True Blast Plus for a steamer? Do you have a link for those?
I guess a GP-30 will be close enough for a F-7? ???
So what about a True Blast II Plus for a steam locomotive? Are there any available for them??
