                            <comment id="46917" author="bugi74" created="Thu, 21 Feb 2013 20:59:58 +0100"  >&lt;p&gt;If a rail is pushed (no matter with direction), as long as the target location has suitable block below, all is ok.&lt;/p&gt;

&lt;p&gt;In this issue (for the push up then down -case), as the rail is not the block being pulled (by the sticky piston and the block above it), it will be left floating in the air (as the block below was pulled one block down. And of course, this is not acceptable for rails and it will pop out.  (Works as intended).&lt;/p&gt;

&lt;p&gt;However, the push down then pull up -version is more interesting. In my test, I actually was left with a floating rail just under a sticky piston, which I think is a bug (although seems this issue is expecting it). Edit: attached a screenshot &apos;floating rail.png&apos; showing the end result.&lt;/p&gt;</comment>
