OK thanks, when you say " locos" do you mean specifically the B unit or the set as a whole, still can not get a clear answer.  The B unit is not motorized and is not defined as a locomotive. And the only technical help available is in Hong Kong, are you kidding me? Is this where the trains are manufactured?

Comment: Does anyone from Bachmann read these messages? You would think that if a customer who just purchased a Williams F-3 diesel and wants to know if a B unit is available would appreciate the business and provide information as to the availability of such a unit. If not, ok and I will move on. But some of my earlier questions about the weak horn and bell should be answered by the company that makes the product, don't you think? The customer service needs improvement.   

671, thanks for the response. If you purchased all 3 units for that price, you got a great deal! I guess the best thing for me to do is to call TW and see if the B unit is available. I live in Baltimore and my great grandfather, grandfather and father were all train engineers for the B&O, so when I see B&O, I go for it! My Great Grandfather engineered the great passenger trains between DC, Baltimore and Chicago way back when. As far as modifying the engine, not sure I would like to do that, your comment about the power supply is probably the issue, my track needs a good cleaning, it is up all year and this may be the problem. But, the bell does not sound, will have to figure that one out. Thanks again for your response and have a very Merry Christmas.............................bw.     

Thanks, this was my first use of this website and I was not exactly sure if anyone would answer. Hopefully, someone at Williams will be able to answer my questions........bw.

I just recently purchased a Williams F3 Diesel A-A set from Train World. The unit is a Baltimore and Ohio 20190. The train runs great but the horn sound is very weak and needs to be activated a couple times before it will sound. I am using a conventional transformer that does not have a bell button, it only has a horn button. Is this a problem that can be corrected and/or do I need an upgrade over my older transformer? Also, the color scheme is great and is there a B unit available to match the engines? The passenger cars are also B&O by Williams and the train would look even better with a B unit. And when was this unit manufactored, I do not see it on your website.......thanks for your anticipated help on these questions..................Bill Walter.
