In 2011 Lionel cataloged the Texas engines. I do not remember any issues with the whistle (Part # 691RSL1017) but maybe someone who has either of the two PRR engines offered can comment on the whistle. If you own the 2019 J1a version and are dissatisfied with the sounds I would recommend calling Lionel service to see if the 2011 sound board is a swap in with the 2019 sound board (Part # 691RSL3724). I do not do repairs because I have ten thumbs. If you have the same condition you could check with Alex M or GRJ if they could do the swap (If it is doable). Maybe if. You are polite and pleasant when speaking to Lionel they will swap out the part. The 2019 part is listed at $79, the 2011 part says to contact Lionel. At that time I think if you had a defective Legacy sound board you had to send Lionel your defective board and they would send you a replacement.
I have the TMCC J1a engine and love the whistle. I also have the Legacy H10 and love that whistle too. Don’t know if I would like it in a J1a though.
