Question: How much does it cost to take Union Station to South Station, there and back?
Question: What's the steepest possible gradient on Fell mountain railway system?
Question: Howcome modern ships don't have smoke trail behind them?

However, the steepest gradient recommended for a rack railway is 1:4, although the Locher rack system was said to be good up to 1:2.<p>The various rack systems use a toothed rack rail between the running rails, with which the toothed driving/braking wheel engages. Thus, the train is effectively locked onto the track. It is superior to the Fell system, which only has a smooth centre rail which is gripped between pairs of wheels for traction and braking. It is therefore not as safe, cannot be used on very steep grades, but has the advantage of being cheaper to install and maintain.</p></div><img src="http://pixel.quantserve.com/pixel/p-89EKCgBk8MZdE.gif" border="0" height="1" width="1" /></div>  </td>  </tr>  <tr>  <td style="margin-bottom:0;line-height:1.4em;">  <p style="margin:1em 0 3px 0;">  <a name="3" style="font-family:Arial, Helvetica, sans-serif;font-size:18px;" href="https://answers.yahoo.com/question/index?qid=20150327204646AAGBFIm">Question: Howcome modern ships don't have smoke trail behind them?</a>  </p>  <p style="font-size:13px;color:#555;margin:9px 0 3px 0;font-family:Georgia,Helvetica,Arial,Sans-Serif;line-height:140%;font-size:13px;">  <span>Posted:</span> 27 Mar 2015 08:46 PM PDT</p>  <div style="margin:0;font-family:Georgia,Helvetica,Arial,Sans-Serif;line-height:140%;font-size:13px;color:#000000;"><div id="">If you look carefully, you should be able to see a bit of smoke and water vapor coming out.
