For a few reason:&lt;p&gt;- The train doors need to line up closely with the glass doors, for obvious reasons. Commuter trains in the US are not capable of stopping so precisely. Usually the trains would have to support some kind of computerized stop-assist in order to be precise enough to pull this off.&lt;p&gt;- Said stop-assist wouldn&amp;#x27;t just be a train feature, it would involve communication with the track, and therefore upgrades to the entire signaling system. Many systems have this &amp;quot;for free&amp;quot; by virtue of being built later. The actual track Caltrain runs on pre-dates Caltrain itself by a wide margin.&lt;p&gt;- You need to run a unified, homogeneous vehicle fleet so the doors are in the same places on all trains. This is the problem with safety doors in large legacy train systems (see: NYC, Chicago) where due to legacy factors there are many vastly different trains all running on the same track.&lt;p&gt;A lot of non-trivial problems where the only solution is vast capital spending.</text></comment>

Look at this station, for example&lt;p&gt;&lt;a href=&quot;http://goo.gl/maps/vmYxx&quot; rel=&quot;nofollow&quot;&gt;http:&amp;#x2F;&amp;#x2F;goo.gl&amp;#x2F;maps&amp;#x2F;vmYxx&lt;/a&gt;&lt;p&gt;The tracks keep going, with basically nothing protecting them. Putting up walls around the entire thing would be a significant undertaking.</text></comment>
