Electronic Steam Whistle
Can anyone help Philip?
“I am looking for a circuit of an electronic steam whistle, perhaps built around a 555 timer.I can find heaps of circuits of train horns but not train whistles. Thank You.”
HO Athearn Genesis
Johnny has an Athearn Genesis and is having problems:
“I have an Athearn Genesis f unit with dc and dcc sound. Everything works great in dc but in dcc I have sound but the loco will not move. I have a digitrax system. I have tried to reset the cv125 to 1 several times to no avail. I even emailed Athearn and they said to reset in dc which I did but all that did was reset the dc only.”

NOTE TO ANYONE ASKING QUESTIONS
It is in your best interests to add as much detail to your questions as possible. Also, explain the problem as clearly as possible – you can even mention solutions you have tried that haven’t worked.
The important thing is this; if the person answering the question doesn’t clearly understand your problem, or know what you are trying to achieve, it is likely the answer will be incomplete or even inaccurate.
The very kind people who share their time answering questions (and giving feedback) are genuinely trying to help, but sometimes it is very hard to offer any suggestions due to a lack of clear information in the original question.
Also, if you do use this free service to ask a question, it would be really helpful if you could add feedback to thank the contributors. They are helping out voluntarily because they genuinely want to help others in the hobby.
One more thing; if you know the answer to any questions posted by others or can add some feedback to a question – please do. This service will only continue to operate if everyone contributes fairly. So, if you ask a question – have a look through the other postings to see if you can help someone else. We all need to help each other.
Use the green Comments & Feedback link below any posting to add your thoughts.

Decals, Road Signs and Track Signs
John is on the look out for decals and road signs for his RR layout and asks:
“Can someone inform me where I can get European decals, road & track signs (Norwegian) if possible?”
You can help John by adding feedback to his posting.
Also, even if you can’t answer John’s question, perhaps you might like to comment on decals and road signs in general. Maybe you make your own road and track signs, or maybe you can share some tips for applying decals. I’m sure others in the hobby would be very interested in hearing your views.

I Need Help From Anyone With Experience In The Hobby
Our recent reader poll results showed 75% of respondents thought other model railroaders were willing to share ideas. Unfortunately, 23% thought some people in the hobby could be more helpful, or that many resist sharing their ideas and knowledge. So, here is your chance to prove the 23% wrong!
If you have any knowledge of model railroading you can contribute your ideas to this blog and help others in the process. Without help some beginners may simply give up and leave the hobby through sheer frustration.
You will know from previous postings I always encourage people to join their local model railroad club, and this blog is also a way you can interact with the wider model railroading community.
Your Thoughts Matter
The problem is, I don’t have the time to continue running this free service on my own. I need others in the hobby to step up to the mark and start helping with answers to questions etc.
At the moment this blog is available as a free service to everyone, but one option is to make it for private membership only. That way I could generate some revenue to cover some of the costs of my time spent running this service.
However, my preference is to keep it as free access to everyone, but I need others in the hobby to contribute their skills and knowledge to keep it going. Fortunately, we do have some very generous, regular contributers like Tony P, Hank, Herb Snr and others… but, they can’t be expected to do everything.
The first thing you can do is register as a contributer and blog member. That way, I know you are seriously interested in helping others in the hobby and helping me (and others) to keep this blog as free access for everyone.
Then, you can simply add your feedback and comments to various posting and share your thoughts and ideas with others. We need this hobby to grow and prosper. We need to continually attract and encourage new people into model railroading. Without them, the manufacturers, suppliers, retailers etc won’t do as well… and we all know what happens when people don’t make money.
I am sorry for the lecture, but it is best I speak my mind, rather than just make changes without giving everyone the opportunity to participate.
So please, we can all help each other. We are all in this hobby together. Don’t just sit there, register now and help others!

Removal Of Train Body From Chassis
Gerry is new to model railroading and it sounds like he is trying to remove the body from the chassis. He will probably need to remove the couplers and squeeze the shell together at the rear and at the front to release the locking tabs. Perhaps someone might like to walk him through the process step by step. Here is his question:
“I need some help getting the shell off a Athearn SD40 model 93567 engine. I am mew to this hobby and need to install a decoder in this and another engine. Does anyone know how to do this?”
Come on! Don’t just sit there. Add your feedback to help this beginner. He needs help and encouragement. Click on the green comments link below and register.

Why Older Model Railroaders Need To Pass On Knowledge To Younger People In The Hobby
Have you got any experience building or operating a model railroad layout?
What can you do to help others in the hobby (especially beginners)?
If you know a little (or a lot) about model railroading, then please join in and add your comments and feedback to the various postings on this Model Train Help blog.
There will be lots of others in the hobby who could benefit from your knowledge and experience. Please don’t just read these postings and think to yourself “I know that answer”, but then do nothing. A little time and effort on your part could hugely benefit several others in the hobby.
We are all getting older and it is critical that experience and knowledge is passed on to younger ones in this hobby.
Please! Please! Share your knowledge and experience with others. We are all in this hobby together. We are not commercial competitors, so what does it matter if someone else knows how you did something and solved a problem? Share your knowledge.
Please help!
Athearn Bachmann Parts
Mike has a problem with getting model train parts and asks:
“I’m retired operating engineer (Heavy Equiptment Operator) 67 years old. My question is why is it so hard to get replacement parts, I have bought a few Athearn, Bachmann locomotives and you call to get replacement parts and the first thing they tell you is there are out of stock and they no longer make that part. It seems to me that the manufactors sell these locomotives with on problems why can’t they make sure they continue to supply the required parts we need to keep our trains running? In the Caterpillar world you can still get parts for tractors made in the late 50’s, and I think the Model train business is as demanding as the Caterpillar world. I really enjoy the modeling world of the HO gauge trains.”

Track Gap Between Connecting Rails
Al is new to model trains and would like help from anyone with some experience in the hobby and asks:
“I am new to this great hobby and having purchased a used layout from another train hobbyist I encountered a slight problem with a bit of track gap. I seem to lose some electrical power where this occurs which causes my locos to stutter before continuing on around my layout. My question: is there something that can close this small gap between the 2 connecting rails. Is there some kind of filler, connector, or insulator.”

Operating Multi Train Control Systems
Nader is wanting to operate multi train control and asks readers for advice:
“I’m looking for a computer/electronic multi train control. I’m trying to build an outside railroad (G sacle) and would like to power and control the train via remote control. Would anyone have a few suggestions? Thanks!”

Homasote on MDF Board
Stuart has two questions for anyone who has used Homasote and asks:
1. I plan to lay on Homasote (compressed paper) supported by MDF boards. Should I use cork underlay as well?
OR
2. If I mark parallel lines just outside where the track will lay and paint glue between the lines, could I lay track then ballast in order minimize the use of track pins which will not hold very well in the Homasote?
All opinions very welcome – I am old but “beginner” status.
Definition: Homasote is a pressed paper construction board often used for model railroad roadbed.
Rail Weight And Crossings In Question
Al wants to hear from anyone with experience with tracks and crossings and asks readers:
“My last layout was made back in the 70’s and it was torn down for a move. I am starting a new layout and wonder what weight rail to use and, once decided, if there is any problem matching it up with turnouts.”

Scratch Built Crossing

HO Layout Track Planning
Dick wants to build an HO layout and has a question for other HO enthusiasts:
“I am just starting to research things before buiding an HO layout. I am an experienced 64 yr old modeler, but have not done railroading in many years. I built highly detailed wooden ships from scratch for years. I’m in to detail. I want to do a train layout with similar detail. I’ve looked at track and some of the combination track (with roadbed) looks toy-like to me. Can someone please give me some specific advice about track ie. Manufacturer, 83/100, track alone or roadbed/track combination, type of roadbed. Thank you.”
