Strange result from ground light rail OnSlope

[Moonraker0 192]

 I'm trying to build a ground light rail OnSlope section over a sunken highway (made with smoncrie's Hole Digging Lots).  I plop the puzzle piece, but get a weird result that can't be right.  Take a look at the attachment to see what I mean.  I'm guessing I'm not doing something right.  I searched around, but didn't find documentation for this specific puzzle piece.  As the picture shows, viaduct rail OnSlope works fine.  I've tried the GLR OnSlope with and without the BRF_TunnelAndSlopeMod installed, getting the same result both times.

The reason this is happening is becsue you are not placing the puzzile piece correctly. The GLR Onslope Piece is longer than the rail one. The entire piece needs to past the top tile of the slope,

To use it correcty, use the "T" puzzle piece. The arrow tile goes on the slope and the second tile goes over the highway like this:

Oh, ok. Thanks for the picture and explanation.
