RMweb Premium Trainshed Terry Posted May 2, 2011 RMweb Premium Share Posted May 2, 2011 Very good, think they might need some more ballast More ballast, more like a bridge to be put in place. :blink: Terry. Link to post Share on other sites More sharing options...
Adrian Wintle Posted May 2, 2011 Share Posted May 2, 2011 They won't put a brdge there. It will be one or two large culvert pipes and then fill and ballast. I expect that there were culvert pipes there that got blocked by debris/ice dams/beaver action, which forced the water to saturate the embankment. Once it reached a critical saturation it liquified and washed away, with hydraulic pressure and erosion completing the job. I've seen a similar situation on a forest road that we were checking when laying out a rally route. We had been warned that there was a 'big washout', but we weren't prepared to find an 8' wide, 6' deep cut in the road (with effectively vertical sides), with a 4' culvert pipe still in place in the bottom of it. Beavers had plugged the culvert and the spring runoff had found a way around. Adrian Link to post Share on other sites More sharing options...
dave1905 Posted May 2, 2011 Share Posted May 2, 2011 Classic method of repair is to instal/replace the culverts (concrete or corrugated metal pipe), then build cribbing of ties to support the track. Depending on water situation, back cars of rip-rap or ballast over the cribbing and dump it in the hole. Once the hole is filled, finish off with ballast and tamp level then dump rip rap to prevent scour and anchor the toe of the slope. Link to post Share on other sites More sharing options...

RMweb Gold PaulRhB Posted May 3, 2011 RMweb Gold Share Posted May 3, 2011 As the guy on the tape says, I think they saved a couple of lives. Imagine the wreck if a freight had hit that or even worse if VIA use that line. I wonder how be did get back to his hirail truck. Link to post Share on other sites More sharing options...
Jenny Emily Posted May 3, 2011 Share Posted May 3, 2011 I wonder how be did get back to his hirail truck. Carefully? I'm guessing that he wouldn't have considered shimmying across those suspended rails a good option, so my guess is that the railway company would have sent another crew out to meet him who would have also been able to help assess the damage.

DonB Posted May 3, 2011 Share Posted May 3, 2011 There was a similar wash-out on the SVR two years ago (if I've got my dates right). Cost them a fortune to re-instate the line. Link to post Share on other sites More sharing options...
dave1905 Posted May 3, 2011 Share Posted May 3, 2011 The difference between big railroads and little railroads, deep pockets. This type of problem is going on right now all through the central US, Missouri, Illinois, Arkansas, Kentucky, Tennessee, with over 20" of rain over the last several weeks. Almost every railroad operating through there has had one or more routes out of service or restricted due to washouts, slips or high water. Typical spring. The biggest problem is getting the ballast and rip rap to the locations quickly. If necessary they will get chunks of concrete or whatever local rock they can truck in for rip rap.

F-UnitMad Posted May 3, 2011 Share Posted May 3, 2011 Okay, I'll be the one to stick my head up and ask the Stupid Question.... What is "Rip Rap", then..?? Link to post Share on other sites More sharing options...
trisonic Posted May 3, 2011 Share Posted May 3, 2011 Rip rap is usually the larger rocks or shaped pieces of concrete seen at the water's edge of dams and other parts of the shoreline that need protection. Best, Pete. Link to post Share on other sites More sharing options...
dave1905 Posted May 3, 2011 Share Posted May 3, 2011 Rip rap is large rock, anything from about a foot and a half to five or six feet in diameter. Boulders. It is primarily used as "structure" in an embankment or as "armor" around an embankment near water. It is normally too heavy to be washed away by all but the swiftest flowing water. It is normally dumped out of side dump cars (when the car tilts sideways and dumps the entire load to the side of the track). Big rip rap may have to be placed by a backhoe with a grasping bucket. Screenings are fine rock, like pea gravel or gravel used in concrete. It is used as fill and for walkways. Ballast is larger rock between 1-4" in diameter used in trackwork. Rip rap is big rock used to protect from erosion and build embankments. Link to post Share on other sites More sharing options...

dave1905 Posted May 4, 2011 Share Posted May 4, 2011 If everybody remembers the thread on the town of Cairo, Illinois, there is a new wrinkle to the story. The Mississippi and Ohio rivers are rising with all the rain. The levees in the area of Cairo were in danger of being overtopped and the city being flooded. The US Corps. of Engineers (in charge of flood control devices) decided to blow up the levees on the Missouri side of the river at Cairo and flood 130,000 acres of farmland to help save the city and its 2500 inhabitants. The 25 farmers in Missouri are not very happy about taking one for the city in Illinois. Link to post Share on other sites More sharing options...

But they did know they were farming the designated flood plain and getting compensation (not sure if it was cheaper land costs or just a grant) for it.

RMweb Premium BR60103 Posted May 5, 2011 RMweb Premium Share Posted May 5, 2011 Stackpool is at mile 105.4 on CN's Ruel sub (Capreol to Hornepayne) in northern Ontario. This is on their main transcontinental line. About 60 miles west of New Likeard/Kirkland Lake and a similar distance northeast of Sault Ste Marie. (This rly does not go through either of those places). North of Lake Huron -- Espanola or Sudbury. The area is very much out-of-the-way, although there is a highway nearby.
