Dear everybody, <br />Hello, I have a number of questions. Any of them you could help me out with would be appreciated. <br />1.) (For the magazine guys) Suppose you have a person named Ms. Smith, and she takes a picture. Later, she gets married and becomes Mrs. Jones, and later submits the above named picture to a magazine. If you were unable to ask her preferance on the matter, how would you write the photo-credit? For example, would you write "Ms. Smith," "Mrs. Jones," "Ms. Smith, collection of Mrs. Jones," etc. <br /> <br />2.) Did any steam locomotives have connections for the independant brake from locomotive to locomotive, or is that strictly on diesels? <br /> <br />3.) Why are steam locomotives' couplers usually rigidly attached to the frame (i.e. no sprigs for absorbing shock, only a pin), or at most only sprung on the rear? <br /> <br />4.) How would the above fact affect train handling on a light engine move of a number of steam locomotives? <br /> <br />5.) If a shipper loads freight cars at a variable frequency, or requires them at non-constant intervals, how does the shipper inform the railroad that it needs an empty freight car or that it has one to send out? <br /> <br />6.) What voltage do traditional signal batteries run at? <br /> <br />7.) While along BNSF's Clovis Subdivision in Abo Canyon, New Mexico, I saw numerous propane tanks along the right of way, near signals. Are they for electricity generation or what? <br /> <br />8.) This is how I understand a freight car moving across the country. Please correct anything that is wrong: The car is included on the switch list of a switch crew to be picked up. The yard switch crew has another list which tells them which train to put this car on. The paperwork is carried on the train, and at each yard where switching is required, a switch list is made up including this car. If the paperwork is lost, the waybill on the car tells where it's from, where it's going, and what it's carrying. <br /> <br />9.) If a UP boxcar is used to haul a load from say Omaha to New York via CSX, once it's empty, will CSX use that box car for a loaded trip back from New York, or will it just be sent back empty to UP. If the latter, how do they decide where on the UP to send the boxcar to? Does CSX just pick a convenient connection point and say "here it is"? <br /> <br />10.) Why is it so important that employees not divulge signal indications over the radio? Is it just to keep the chatter down? <br /> <br />11.) What is the difference between a waybill and a bill of lading? <br /> <br />12.) Back in the days of cabooses, and I assume still today, what kind of paperwork would the conductor have to do, assuming no delays and no accidents? <br /> <br />13.) Why are there two air brake connection hoses for the independant brake from unit to unit? Would not one hose be sufficient? <br /> <br />14.) Would somebody please be so good as to explain the basics of two-hose/graduated release braking systems to me? <br /> <br />15.) What does the dead-in-tow engine feature on the brake system do? Specifically, why couldn't you just use the engine's normal braking system, with the stand cut-out, in the middle of the train? <br /> <br />I realize that I'm asking a lot of questions here, but any help you could provide would be greatly appreciated. <br /> <br />Gratefully, <br />Daniel Parks
