Here is the latest on my 1960s Pressed Steel Limited Roadrailer -:

- I will post updates here, and requests for comment as I produce the model.

 

I am still looking for more details of the underframe mechanism and coupler operation.

.... also good news,  I have located a surviving one in the USA at a small railway museum in Sparta Michigan   - and through some e-mail dialog I have had with a lady at the Sparta Township Historical Commission, a kind gentleman is going to get me some detail photos of the coupler mechanism etc  for me  :yahoo:

I have the original roadrailer manuals, passed to me from the former project manager. Also pressed steel literature etc. Happy to share!

slowly working up the detail on the underframe, you can see why it had strength problems !

..... but actually, now I have modelled it again, using the actual dimensions from the GA Drawing - it looks a bit stronger -:

Yes it will be fully scalable, you will loose a bit of detail at the smaller scales and the kit may be a bit simpler but it will all work.

 

Have done a bit more -:

.... please can you get in touch ? - I am struggling with getting enough info on the brakes - perhaps the 'manuals' may give me some help.

Will the body be hollow orvserator seperate sections to join ?

If it one solid piece it will add to the cost.

Seperate doors at the back at least would be good as it would provide an easy solution to have the rear doors open

...... at present I have not gone for openable doors, but it is hollow - I may look at doing it but it will involve more scale fudging to make it possible.

 

I am doing the pre production, and production variations now.

.... looking for ideas as to what other modelers do or what people actually want from a kit ? - the scalecraft kit version has 16 rivet heads of around a scale .75 inch diameter spaced approx 4 inches apart (this gives the idea of it looking something like real but is not) -  in reality there are 38 .375 inch rivets spaced 2 inches apart - will this just be unrealistic at a scale size - in my test they are barely visible at 7mm scale to the naked eye, but look good with a magnifying glass ! then at 4mm they are there but barely visible even with the magnifying glass.

 

Do people just want a reproduction of the scalecraft kit, with more correct details in certain areas - for exmple the roofline, wheels tucking under etc. ?
