q3dm17 comes with Q3Radiant as a sample map, The Rail Yard map is a small conversion of this sample. All weapons have been replaced with Railguns, all ammo is now slugs. Now add another quad platform (like one quad is not enough right?) - then throw in two BFG's in what is almost the worst weapon placements I've ever seen. And that is it.
Why include the BFG at all on a Railgun practice map? No bot file included too.
