I searched for trains from Akola (AK) to Nagpur (NGP) on 24th September, 2014. One of the trains shown is 09535 Hapa - Bilaspur SF Special. However, when I click on the train details, it says that the train runs only between Oct 07 and Oct 28. If so, why did the train show up in the search results at all? Is it expected behavior or a known issue? I'm attaching a screenshot to illustrate this issue.
