Clarification for 1,009mm and 1,013mm gauge[edit]

In the Tram track gauge and Metre gauge article, a gauge of 1,013 mm was specified for the Sofia Tramway.

No proper sources exist for 1,013mm, only an anecdotical source from a [http://www.skyscrapercity.com/showthread.php?t=450211&page=28 blog], Facebook and a A Finnish site. The anecdotes tell (sic)

After the (World) war (2) it was changed to 1013 mm due to the terrible track condition. That was the only way the tram network in Sofia to keep it's license from the state rail inspection. After this, the gauge standard is slowly narrowed step by step back to the 1000 mm. 1009 mm is just one step back towards the 1000 mm standard gauge.

In fact, the German interwiki, Straßenbahn Sofia tells almost the same unsourced anecdote, but dates the event at 1927, when due to wear and tear the gauge exceeded its allowed tolerances. To avoid expensive replacement of the tracks, the gauge was formally widened from the original 1,000 mm (3 ft 3+3⁄8 in) metre gauge to 1,009 mm (3 ft 3+23⁄32 in) to keep its license from the state rail inspection, and the stock was converted to 1009 mm:

Nachdem der Rückkauf des Straßenbahnbetriebes von der belgischen Firma im Jahr 1927 abgeschlossen wurde, stellte man fest, dass der Zustand des Schienennetzes miserabel war. Die Abnutzung war so groß, dass es nicht mehr dem Metersprur entsprach und es wurde beschlossen statt einen kostspieligen Austausch der Schienen vorzunehmen einfach die Spurweite der Wagen zu verändern - diese wurden dann auf 1009 mm umgespurt.

I think it's safe to assume that all 1,013 gauge mentionings can be removed (as enough references for 1,009 mm do exist).--Aaron-Tripel (talk) 20:06, 5 May 2014 (UTC)[reply]

"the stock was converted to 1009 mm". This could only have been done by a bogie exchange or by a wheelset exchange. Train wheels don't move on the axle because of an interference fit. Peter Horn User talk 01:54, 9 May 2019 (UTC)[reply]

Moving line closures from the "lines" to "history"[edit]

It seems weird that all historical info about the lines is in "history", but line closures are in the lines category. For clarity, it's better to put all historical information in "history" and the current lines and routes be in "lines". Sasujberg (talk) 21:11, 8 August 2023 (UTC)[reply]
