Slipersfråga (Bana)

av nicke, Tuesday, January 29, 2008, 16:13 (6153 dagar sedan) @ Bengt Jönsson

GHJ byggde järnvägsspåret mot eken 1976-78 med oimpregnerade slipers. 1987 var alla slipers slut. Alla 1538 slipers Hy-Ekn byttes i rask takt ut de kommande åren därpå. Efter den smällen så är all slipers impregnerad.

Som parantes kan nämnas att (gummi) järnvägen Madeira-Mamore´ i Bolivia/brasilien hade stora problem med sina inhemska slipers tillverkade av regnskog. Termiter och annan ohyra knaprade upp dem, så de var tvungna att importera motståndskraftig slipers för 366 km från nordamerika...
