Talk:Passenger railroad car/to do


 * The use of aluminum for car bodies should be mentioned.
 * Add images for each of the car types mentioned. (I've got a combine and a heavyweight obs, I'm looking through the rest of my photos for other types now.) (only really need a lounge car image now)  slambo 18:06, Nov 21, 2004 (UTC))
 * Add any car types that are missing. (I think I've got all the major types. slambo 12:08, Nov 22, 2004 (UTC))
 * Expand to include car types and practices from outside the US. (Is there really any difference here? slambo 18:06, Nov 21, 2004 (UTC))
 * Describe the differences between heavyweight and lightweight car types
 * Objections from Featured article candidates page:
 * The lead section should be expanded to at least two paragraphs, and provide a summary of the entire article. See Lead section.
 * History section stops in the early 20th century. Should be expanded to modern day. (but it could still be improved with details on other modern technology advances)
 * References are inadequate. The only reference doesn't seem to cover most of the content, and certainly not the more recent content.
 * However, as many of the articles going through FAC now are being objected to due to a lack of inline citations, this part of the references problem will need to be addressed.
 * Units should be presented in at least metric units, or both imperial and metric, but not in imperial measures only.
 * A lot of potential information is missing. Who manufactures passenger cars? How many passengers fit in the average passenger car? What are the dimensions (length, weight, height)? How many are pulled by a train? How do they compare with passenger cars in for example metro systems or trams?
 * Add information on military uses of passenger cars and specialized passenger cars used by the military (i.e. troop cars, troop sleepers, hospital cars ).
 * Discuss how newer technology (e.g. talgo tilting technology) and different design elements (e.g. lower center of gravity for faster trains) have been applied to passenger cars
 * Provide the range of weight for US heavyweights (75-100 metric tonnes ?) and streamliners (45-75 metric tonnes ?) and for cars in other countries mentioned in the article
