PH14: Making Tracks

The train enters on the left, connects all the given pieces, and exits on the bottom. The numbers indicate the total number of segments of track in that row or column. Track pieces can be straight or make a 90 degree turn. The track cannot cross itself. Gray squares on the main grid must contain a track.

To lay down tracks, you can either drag between cells or click on the edge between two cells. You can also click the interior of a cell to mark it as being on the track, or right-click to mark it as being off the track.

Read every seventh letter along the track to get the answer.
