Hi MF,
Hi Gadge,
I remember a news report covering floods showing a 44 class bullnose locomotive very slowly going over tracks suspended in the air from track bedding being washed away! Some were a few metres long from memory and visibly flexed but held. Can you imagine them allowing that these days?
No way known! But things were very different back then - no mobile cranes, except for rail-mounted ones...
I never knew there were different thicknesses of track itself for railways. I have seen thinner rail used for secondary uses in boat ramps and mine shafts but never knew the same rail network used varying grades of track.
Yep; here's a pic of a piece of 10 lb/yard rail, from one of the many 19th century abandoned gold mines, in the hills North of where I live.
