I mean if you actually set the Republicans in the Senate physically on fire and Obama walked up with a fire hose, do you think they would let him put them out, or do you think they would stonewall so they could sit there and burn just because it was him trying to put them out?What about the Democrats? Do you think if they were the ones burning, they'd have the same response if, say, Boehner or McConnell were the ones holding the hose?
Let us not forget the loose wheel detector.
galvanized is bad, old houses have galvanized pipes. Galv pipe corrodes and reacts with minerals in water causing blockage and disintigration. Copper is best - but can get expensive.
There are several types of Defect Detectors: A, High-Wide DetectorLooks like a metal Rectangle going over the tracks, used mainly in areas where tunnels are located. They are used to measure the cars of the train to make sure they will clear the portals of the tunnel. B. Hot Box Detector A small metal block with heat sensors that measure the temperature of the trains wheels as they go by. Used to check for Hot Axles, or journals. If this detector goes off, the conductor of the train has to stop and check 12 axles fore and aft of the specified axle, if the axle is hot (the heat will radiate) the crew will need to set the car out. If there is no available place to set the car out at the current location, the train needs to be moved at no more than 10 mph (higher, the car could derail) to the nearest setout track to set the car out. A hot axle or journal is caused when the wheel builds up to much friction. C. Slide Detector Fence Found in mountain areas or in areas (such as canyons) where Avanlanches and Rock or Mud Slides are common. If any of the above trips the fence, all signals in the surrounding area will go to a stop indication until someone (maintainer usually) can look at the area to make sure there is nothing wrong. D. High Water Detector:Found on bridges if the water under the bridge gets over the detector all the signals in the immediate area go to a stop indication to prevent a washout. A Track inspector will be summoned to check the area to see if it is safe or not. These are the 4 main detectors. I hope this helps
