Posted by Train Man Paul : Metro-North's Best Conductor FOR ALL 3 LINES!!! on Sun May 6 21:25:52 2012, in response to Re: Best Article I've Read on Reasons to Reactivate the Rockaway Beach Line, posted by clearaspect on Sun May 6 19:52:53 2012. Alot of bridges during those times were overbuilt and are quite strongSpeculation at best about strength. Remember they have sat moribund, in about 70 years of snowstorms, rainstorms, heat expansion from heat waves, extreme cold, humidity, corrosion from water and other chemicals in the water, stuff that might have been dumped on the right of way, etc. etc. Would you really take a chance running full time service over old structures which been thru those conditions without regular inspections much as you would have if they were open for rail service, and inspected on a more regular schedule and routine maintenance schedules? They may look broad and "overbuilt", does not mean they are in the condition to support heavy cars at regular frequent intervals on a 24/7/365 basis? These structures will indeed more than likely need to be completely rehabbed, if not completely replaced with newer structures. But to show the strength if you visit the Sea Beach line alot of the bridges over the line are nearly 100 years old. You cannot possibly compare roadway bridges to structures designed to withstand heavy trains at frequent intervals. How many cars passing over a roadway overpass would it take to stress that structure in terms of weight on structure to measure up to and equal the weight of either 8 or 10 empty passenger railcars, much less ones with load, at a similar frequency, and the stress that causes to a structure?? Do any of those roads see heavy vehicles such as frequent heavy or wide load vehicles other than occasional trucks and city buses?? And do any of those vehicles in any number add up to the weight of 8 to 10 passenger railcars (again not gonna even factor in loaded cars), and how many would it take to equal the weight of 8 to 10 passenger railcars?? |
