Updating template map of Western Rly, Austria (Oct 2016) - First half
I've updated the template map used by English page article Western Railway (Austria). The map originates at Template:Western Railway (Austria).

Updated using German article version at https://de.wikipedia.org/wiki/Westbahn (Österreich) as the German hardcoded map is more up-to date than the English template which is unrevised since 2009 and badly out of date for details of the "new Western Railway" improvements. Also used http://www.oebb.at/infrastruktur/en/Servicebox/Brochures_and_Folders/2009_04_Wien_-_St._Poelten_englisch.pdf as information source for improving some old/new line references.


 * Removed duplicates of 41.461 Ollersbach, 43.558 Kirchstetten and 49.076 Böheimkirchen.
 * Corrected 49.846 Tullnerfeld 4 crossover and Sieberg Tunnel positions.
 * Then amended or added lines as per the German version.
 * Also added Wienerwald Tunnel west portal kilometrage and moved its position (shortening its length on the map).

Revision tested and fully checked here. All shows okay for the first half, ie. lines 0.000 Vienna West through to 107.137 Ybbs an der Donau.

Updating template map of Western Rly, Austria (Oct 2016) - Second half
SECOND HALF of MAP (lower down), revised using German article version at https://de.wikipedia.org/wiki/Westbahn (Österreich), as more up-to date than the English template unrevised since 2009.

Tested and checked here as a separate second "BS-map" of 110.887 Neumarkt an der Ybbs-Karlsbach to Salzburg Hbf. But hit a problem with both BS-maps on the same page. Kept getting a resulting "Warning: Template include size is too large. Some templates will not be included.". So I shortened the overall text size by using the abbreviated "ÖPNV Wien" template instead of the default "Public transport Vienna" template (and similarly changed "Public transport Vienna" to "ÖPNV Wien" usage). But still too big, over the limit when attempting to include the last 4 lines ("Salzburg-Tyrol Railway from Wörgl" to "0.000 Salzburg Bhf"). Therefore I can only test that the whole revised BS-map will display okay (ie. is below the template include size limit) by now deleting the "first half" and "second half", and testing all lines together as a single BS-map (ie. text size will be reduced because I won't be duplicating the BS-map header line).

Updating template map of Western Rly, Austria (Oct 2016) - The whole map
WHOLE MAP (lower down), revised using German article version at https://de.wikipedia.org/wiki/Westbahn (Österreich), as more up-to date than the English template unrevised since 2009.

Result is still "all bar last 4 lines" (anything more invokes a template include size warning). Maybe it won't allow more than 290 lines max? The map is composed of 294 lines...

Ongoing: The German page version has about 312 lines, so there's no line max - just a text size max (although the German version is hardcoded in, rather than being called as a template). Ah! Abbreviating "old/new Western Railway" to "old/new Western Rly." enables 291 lines to show (leaving 3 to go).

Ongoing: Abbreviating blank cells (by shortening "|}}" to "}}") should help further (38 instances), but doesn't help enough. Still 291 lines max.

Ongoing: Annoying! 291 lines show okay in "preview", bu when saved NONE show and instead the result is a link to the Template:BS-map page (where it incidentally suggests using a superceding Template:routemap as it will load quicker and be a shorter text-size). What? Start all over again? I'm going back to 290 lines to have a further think about whether this updating is a waste of time.

Pershling Bridge
Added Pershling Bridge because:
 * It helps to explain why the 3 tunnel chain (Reiserberg, Stierschweiffeld and Raingruben) is also known as "Tunnelkette Pershling" (lit: the Pershling Tunnel chain).
 * Other new bridges/viaducts are included on the map, with their metre spans.
 * Source http://www.oebb.at/infrastruktur/en/Servicebox/Brochures_and_Folders/2009_04_Wien_-_St._Poelten_englisch.pdf states "In the open air section between the Stierschweiffeld and the Raingruben Tunnel, the route crosses the river Perschling with a 117 m long and 13.1 m wide prestressed concrete bridge." I checked on a map and it's between the Stierschweiffeld and the Tullnerfeld 4 junction.

Other notable improvements

 * Swapped positions of "old/new (Loosdorf bypass) line" and "(76,946/76,951) break in Km", and then reduced the 76.946 two-rail markers to just a single rail marker, as German version states the Km break applies to old Western Rly. only. All to aid clarity.
 * Amended all 19 instances of "break in kilometrage" to state "chainage break" instead. Austrians and Swiss engineers call them "Errorprofil" markers on the rail line, and Germans use the term "Kilometerwechsel", "Kilometersprung" oder "Kilometrierungssprung". The French use the term "Kilométrage". British construction engineers use the term "chainage" and "chainage break". Saves 19 x 6 characters = 101 characters shorter. It should enable the addition of an extra line (as still too big to include last four), and the next line is only 89 characters long. But it doesn't - it still won't take an extra line without warning template is too big!
 * Also moved a second chainage break at (91,925/92,230) and narrowed track, so that the break shows as one pair against two parallel lines (instead of two pairs against separated lines. I checked a satellite view of the location (1km east of Pöchlarn) first, and it confirms the lines return to running side-by-side for some distance before that point.

Altitude of Wienna West Bahnhof
English page version says station is at 167m above the Adriatic. German page version says it is at 198 m above the Adriatic. Which one is correct? http://www.floodmap.net/Elevation/ElevationMap/?gi=2761369 has an elevation map of Vienna generated using elevation data from NASA's 90m resolution SRTM data. The station is at Funfhaus district, an area that the floodmap shows as being between 194m and 223m above sea level. The English version seems to match the city's lowest point (the Danube river). The German version seems more accurate for the station, so I've amended the English page altitude to match the German one (ie. 198m altitude).
