Can anyone tell me if this formation has a name?

Hi Tim,

Many thanks for that.

I don't know a name, but it allows the siding (spur) to depart at a sharper angle than would be possible with a simple turnout. If you swing round you can see that the track is required to enter a doorway:

http://maps.google.com/maps?f=q&hl=en&q=Brooklyn,+Kings,+New+York&sll=37.420106,-122.085314&sspn=0,359.972363&g=Brooklyn,+Kings,+New+York&ie=UTF8&cd=1&geocode=FaKnbAIdnUqX-w&t=h&layer=c&cbll=40.648089,-74.021551&panoid=eJZfgxQj76k9Q_xxtczTAw&cbp=12,165.9874793312645,,1,17.386620090776297&ll=40.648022,-74.02162&spn=0.001451,0.002414&z=19&iwloc=addr

In some cases it can also save the need for a facing-points lock, or bring the points within the 350yd. limit for mechanical rodding from the signal box.

Here's something similar:

Those interlaced timbers must make tamping the ballast a nightmare

You can see in this bird's eye view of the same location that the siding enters between the buildings, and a very sharp curve would have been needed for an ordinary turnout:

An American colleague has pictures, somewhere, of the actual formation. He is familiar with the area and says that the spur is no longer used. Went on to add that it wasn't an unusual idea and the idea, with variations, has appeared in various track 'planning' books. He didn't know if the formation had a name.

Thanks for the replies. I didn't think it had a specific name, but the logic behind it seems obvious. The pic of the British example is interesting (and far more complicated, when combined with all the other pointwork)

I don't think facing point locks were an issue in this case!

Its pretty cool being able to trace a railway using Streetview.

Another site that insists you use IE.

Hi John,

It's working fine in Firefox here.

In fact in Firefox I have yet to visit any site which insists on IE, although I'm told there are some.

regards,

Martin.

I had not tried Firefox, but have since suceeded. Google Chrome also works. I wonder what they have got against Opera?

I was wondering, I created the link in Chrome (my IE has become a bit flakey and locks up when using Google maps) and I've just tested it OK in Opera (V9.50) too. Now if MS Live maps that Martin linked to only worked in IE I could understand!

It might not have a name but a friend in New York has a good picture of it and was good enoough to send me this URL if anyone in Templot Land is interested.

There was one similar formation at Romford Goods Depot where the line took an abrupt turn thru a tunnel under the main GER line to reach Ind Coope's brewery. I believe that there is a photo in Dave Brennans' "Ilford to Shenfield" (sic) book.

Best, Pete.

somewhat similar to this http://www.flickr.com/photos/kevin-staddon/4793003482/in/photostream I took in Santiago de Cuba a few years ago. Actual old street tramway as opposed to heavy rail.
