Talk:Balloon loop

message: This is mentioned twice, and I don't see how the track arrangement (or any track arrangement) can be a Mobius strip, which is a 3d strip?

replies: text: Have changed the reference to "Möbius loop" to "figure 8 loop", because if it were a Möbius loop, then on alternate trips around, the train would be hanging from the lower surface of the tracks instead of running along the top as normal. I have not wikilinked "figure 8 loop", because it's not shaped like a knotted rope. --Redrose64 (talk) 09:34, 27 July 2009 (UTC)

message: From the lead: 
Balloon loops do not include track layouts where combinations of junctions allow a train reversal, where this reversal is not regularly used.
.What this is supposed to mean? A balloon loop is a track layout, which may or may not be in actual use. By the same token, a disused platform is a platform. Besides, a 'combination of junctions' can be used to describe  to a reversing triangle, which is a completely different beast :-) --Jotel (talk) 08:32, 22 November 2007 (UTC)
thread_title:  reversal not regularly used.  

message: "Since rolling stock reverse direction in a balloon loop, the couplings and brake hoses must be reversible."
This seems to me to be wrong -- the entire point of a balloon loop is that the train does not reverse direction, it just does a "U turn" with the carriages still in the same order and in the same direction. Unless there is some other interpretation of this sentence that someone can point out, I will be removing this sentence shortly. —Preceding unsigned comment added by Questwolf (talk • contribs) 
:This has to do with uncoupling and coupling sets of cars. For example... Section A; Car 1, 2, 3, 4, 5. Section B; Car 6, 7, 8, 9, 10. Couple those together to make Train 4580. Car 1 is North, Car 10 is South. Run around the loop. Now Car 10 is North and Car 1 is South. Uncouple Section B and add it to Section C which is Car 11, 12, 13, 14, 15. The new Train 4590 consists of (N) 10, 9, 8, 7, 6, 11, 12, 13, 14, 15 (S); alternatively (N) 11, 12, 13, 14, 15, 10, 9, 8, 7, 6 (S). Each set can't be counted on to be facing the same original direction. This would cause problems if the couplings and brake hoses were one-direction only. Hope this helps.

thread_title:  Strange sentence 

message: If Newcastle upon Tyne station is to be included, then Birmingham New Street should be also: it has a stronger case - the existence of triangles at Soho, Perry Barr and the larger triangle between Proof House Junc, Aston and Stechford mean that trains from Wolverhampton, Walsall and Coventry may enter/leave at either end; similarly, triangles at St. Andrew's and at King's Norton mean that trains from Derby or Cheltenham may enter/leave at either end. --Redrose64 (talk) 14:57, 26 July 2009 (UTC)
thread_title:  Newcastle upon Tyne 

message: Liverpool is not included. Is there a limit to the number of stations on a balloon loop? On the Wirral Line, trains arriving at Liverpool through the Mersey Tunnel always fork left at Mann Island Junction, before reaching James Street (platform 1); they then pass through ,  and  before reaching James Street again (platform 3), then rejoin the original route at Mann Island Junction and then pass back through the Mersey tunnel. I make that either three (if you exclude James Street) four (if you count James Street once) or five (because Mann Island Junction is at the end of James Street which is furthest from the loop). --Redrose64 (talk) 15:12, 26 July 2009 (UTC)
replies: text: That doesn't sound like a balloon loop to me at all. That sounds like creative use of junctions that create a looped route. For example, in New York City, a train can leave the lower level of the Archer Avenue Line and return to the upper level without reversing; Not a balloon loop in my understanding. Acps110 (talk) 19:23, 26 July 2009 (UTC)
replies: text: I'm curious as to why you accept the Piccadilly line but not this one. Perhaps I didn't make it clear - it's not "creative use of junctions", because only one junction is involved, that at Mann Island Junction. The platforms at Moorfields, Liverpool Lime Street and Liverpool Central at a deep level, and are only accessible via this route. For example, Moorfields is a station with three platforms - two are at low level on on Liverpool's Northern line, one is at deep level on Liverpool's Wirral line; there is no physical connection which trains may use. Similarly, Lime Street has nine platforms in the main station on the surface; one at deep level on the loop of the Wirral line, and there is no rail connection. See the diagram at Wirral Line, also that at Merseyrail#Merseyrail lines (the route coloured green). --Redrose64 (talk) 20:44, 26 July 2009 (UTC)
replies: text: My apologies! I was thrown off by the statement of separate platforms at James Street. (Inserting another junction mentally there.) Thank you for the clarification. (and further reading on my part). Go ahead and add it to the list. Acps110 (talk) 21:23, 26 July 2009 (UTC)

message: If Liverpool qualifies, then so must the Heathrow loop of the Piccadilly line (Hatton Cross-Heathrow Terminal 4-Heathrow Terminals 1, 2, 3-Hatton Cross). --Redrose64 (talk) 15:20, 26 July 2009 (UTC)
replies: text: Yes, the end of the Piccadilly line is a balloon loop. Only one way in and out for trains using the loop. The fact that the line also includes a stub-terminal is irrelevant. Acps110 (talk) 19:25, 26 July 2009 (UTC)

message: Redrose64 left me the following question on my talk page, and I think the answer is worth recording here.
:Re ... balloon loops on tram systems were indeed common, but the majority of UK trams, whether of the traditional variety or the modern (Manchester/Sheffield/Croydon/etc.) type, are double ended/double sided; indeed I don't know of any system that used single-ended/single-sided electric trams (horse trams are a different matter though). Do you have examples of single-ended/single-sided trams? --Redrose64 (talk) 16:46, 2 July 2010 (UTC)
thread_title:  Balloon loops and single ended trams 

message: Sorry. What does the tram operation video have to do with this article?! I honestly can't tell. This article is about balloon loops. The tram in the video appears to pass through a wye (a.k.a. triangle), and doesn't even make use of it to reverse direction. Pretty video, but pointless here. —Voidxor (talk | contrib) 05:00, 9 December 2010 (UTC)
replies: text: It's been six weeks with no reply. I'm going to go ahead and remove the video. If anybody justifiably objects, feel free to revert. —Voidxor (talk | contrib) 07:07, 24 January 2011 (UTC)
thread_title: Tram operation video

message: Reading the description of a balloon loop, I would think that perhaps the Epcot line as it visits the TTC at Walt Disney World would be considered a balloon loop, being as it never reverses direction on the line, it simply leaves the station and makes a big loop around where the track then parallels the previous track.  Also once arriving at Epcot, the train makes a big loop through the park and then a single beam passes through the station.
