Posted by Rail Blue on Mon Aug 15 04:56:23 2005, in response to Re: SAS termini questions, posted by stephenk on Sun Aug 14 16:36:37 2005. Here is a link to my idea for creating a very high capacity but compact 2 track/island platform terminal.http://www.flickr.com/photos/stephenk1977/27424718/ It simply replaces the scissors crossover with a flying junction. The inbound and outbound tracks would enter the flying junction in a vertical arrangement. It would also allow for flexibility in island platform size (as with a scissors crossover, the further apart the platforms, then the further out the end of the crossover will be, with negative impacts on capacity). Very nice, Stephen. The only problem I see is that at least one of the following three will almost always be cheaper and have the same or better capacity: 1) Passenger Loop 2) Non-passenger Loop 3) Partial relay in station, partial relay beyond station I do, however, agree that flat crossovers at termini are often a nuisance. I've lost count of the times my District's been held going into Wimbledon because something was leaving platform 4, only then to arrive and find the other three platforms empty. |
