Reverse Superelevation ?

I think you'd need some pretty massive washers to get close to the weight of a Bachmann wheelset.

Bachmann metal wheelsets don't sit too comfortably in some Aristo axle boxes either. But all new Bachmann & Aristo stuff comes with metal wheels as standard - otherwise it's £10 a pop for 4 axles :crying:

And another little wobbler - some of the earlier Bachmann plastic wheelsets were a bit tight on back-to-back measurements, and ride up over the check rails on the points - not even worth giving away.

Yes, bit easily fixed, as the wheels slip onto the axle in two halves. Just wriggle them back out to the correct back to back, drop a bit of your favourite glue on the now exposed centre of the axle, and that should fix it.

Te he - how times have changed!

Bachmann metal wheelsets are no longer £10 a pop (I wrote that 6 years ago :D:D:D ) and your fix is now a definite value for money possibility.

I may even have a few axles that I dind't throw away :giggle::giggle: although I now need the large wheelsets having moved most of my stock up to 1:20.3.
 
wow, I read this thread from the beginning... to put it mildly, insanity.

wrong calculation of scale weight, reverse superelevation, just crazy stuff.

And yes, stuff is WAY more expensive now, good thing I bought over 1,000 feet of SS rail and switches when I could, I think I'd have to sell my house now!

(sort of funny reason that Gavin resurrected a 6 year old thread, cannot find the post he quoted)
 
Recently came across this old image, taken from the hill just South of Alp Grum, that illustrates some of the basics argued about in this entertaining thread:

Note the gradient. Oddly most folks, on first glance, assume the image is from a model rail layout.

Didn't realise that those twin tracks came so closely together on the Alp Grum curve....hier-ein-bernina-express-nach-356277.jpg

I didn't like to complicate the issue ;).

PS - you should have climbed further up the hill for a better view (and adjusted your exposure!);).

Pwhoar - I don't think you should be encouraging Gizzy to adjust his exposure - I mean the bow tie with a suit is bad enough............ :D:D:D:D:D:D

Wasn't my photo. One I found on line to confirm that the six foot is more like six inches....

Not sure if this will work but try this link for a closer look:

- hide the lower right imagery for a better view. It's always enjoyable to see the RhB in action and showing how railways should be 'done'. Wish they would open operations in Scotland!

Thanks for that GNB!

I can't though quite understand the reason for this short section of double track where trains can't pass, and I wonder why it isn't single as it used to be?

Perhaps someone can enlighten me....

It's not that recent a change as I recall. My original image (above) is from about 2007.

On your second point. I think it's because of the tight space between the North entry into Alp Grum, (constrained by the protective tunnel) and the Southern exit, (constrained by the sudden change in elevation) forces the construction of two separate but not quite overlapping loops both of which must be a the limit of the operation radius for the RhB. There's simply not enough space to run the station passing loop into to one exit. Look at where the platforms are sited on the Southern side of the station and note how the left hand loop swings out before cutting over to avoid the steep drop to the South. The space in the station section can get quite full with longer tourist trains (think Allegra), maintenance and freight trains and, in the winter, the snow plows/blowers and other emergency gear. The RhB rarely stops running.

Edit - correction my image was taken (by me!) in Sept 2008. Here's a link to a video showing a train traversing the new loop just after completion circa mid 2007 - sometime prior to the introduction of big hauling and longer Allegras'. Hope that casts some light on your query re timeframe.

As an aside an alternative way to see the Rhaetian Special railway collection is via the ever popular "Live Swiss Railways Network" (an interactive animated map based on the official timetables ) via this link:

http://maps.vasile.ch/transit-sbb/

  • Navigate to the RhB station of your choice (text entry in the time box, you can cut and paste into this box), for example try, Alp Grüm, Poschiavo, Switzerland.
  • Select Satellite view, then drag the yellow walking man over the railway line and look out for the dotted circle and small popup that says "Rhätische Bahn, Rhaetian Railway Special Collection.
  • Drop the yellow man and your in business!

Avoid dropping into a tunnel where it's a bit dark (but can sometimes be interesting. Gives a slightly less cluttered view than the straight Google version and you get the fun of the red dots (live trains) passing through the images.

Note: It only works on the RhB and not SBB (yet) and you can accidentally stray onto the road view when they come close to the railway. Internet links only work through the Google Maps.

Here's a test of a few more random Google links to whet your appetites

Yep. you would need a very long curved point to join the loop lines - not practical on such a curve so they run both lines round the curve.
Prototype for every thing!
