Question Atlas 90° crossing ?

Hello,
My name is Chris and I live in France. I'm a huge fan of Hornby and Jouef trains. I use Hornby/Jouef track and I'm plannining to use one Atlas 90° crossing (unfortunately Hornby doesn't make this kind of stuff) for my layout.
Can they work together ?
Many thanks for your answers.

It should be OK as it is the same rail height and the same gauge width. I dont see a problem using it.

Bonjour Chris!

I tried using various Atlas components, including 45 degree crossings,
because Atlas track is cheap and abundant here in the USA, whilst Hornby is expensive
and practically non-existent. I had many, many troubles with the flange being too deep
for any Atlas turnout or crossing point component, I am sorry to report. I thought perhaps the Bachmann British Range would work better, but found, to my dismay, that it was worse.

I tried filing out the point component with a file, and found it did not help at all. Now, I
have heard others report that they do this intermix all the time with no ill effect, so
perhaps you could try one as an experiment before you go into it too heavily- as I did.

Best of luck, would be fine to see some pictures of your work in progress.

Is it a case that the flangeways may not be deep enough? I normally think of Atlas being code 83, which is why when I saw code 100 that I was surprised. I know in the USA that 90° crossings are quite common. They were common in the UK in the past, especially in dockland track formations, but these days they are rare.

UK Permanent Way Engineers do not like Diamond crossings or the 90 degree versions due to the rail damage the wheel flanges cause to the nose of the diamond! They prefer movable angles to a diamond etc!

The flangeways on the older Atlas stuff I tried was Code 100, and though I thought it
should accommodate Bachmann HO British range, I had all manner of trouble with the
pilot riding up upon the flangeway. Hornby OO would visibly jump passing over flangeways.

Careful inspection revealed no gauge issue, but the flanges did just clip the base of the flangeway. I tried filing it down, but with no improvement. Then, my experience might be unique.

Isn’t Bachmann British outline OO? I hope so.

Atlas Ref 176 is Code 100 http://www.gaugemaster.com/item_deta...code=Atlas+176

Atlas 577 is Code 83 http://www.gaugemaster.com/item_deta...code=Atlas+577

All current British OO stock should run okay on Code 83; older stock with deep flanges will have problems and some may have problems on the Code 100 due to finer tolerances that exist today (compare a 1970s Peco Code 100 point with a current one).

Yes and No! Bachmann is also a USA HO scale producer too!
Bachmann Branchline is the UK one.

If the rail profile is Code 100 then all UK stock should run on it correctly, this includes modern and much older items. Flange-way clearance is a another issue totally and nothing really to do with Code 100 rail and is governed by the distance between check rail and stock rail or through a frog. Equally an issue, but is mainly limited to older stock from the 1960's to 1980's, is excessive wheel flange depth!
Code 83 rail profile should run modern stock with especially RP25 wheel standards. But wont connect directly to other Code 100 rail without the use of adaptor tracks or stepped rail joiners

So are you saying Bachmann make HO British outline in the USA FB? I didn’t know that.
