I hate to continue being the harbinger of bad news but dropping the underpass 2 inches does not solve your problem.  Even to climb only 4 inches at 4% grade you need 8 feet of track, but right now you don't have that. 

I'm playing around with your SCARM file but it will need a major redesign to get that grade to work, I don't know what the original layout looked like but from everything I can tell it just doesn't work.

Grade is calculated as Rise Height / Grade Percent (in decimals) = Rise Length.

So, to go up 4" / .04 grade = 100", which is 8.3 feet! 

As far as grades, 4% is the absolute steepest you want to go.  I have a 4% grade on mine that the engines can make up but the smaller cheaper (and lighter) ones struggle on.  So you need a nice long track wrapping around the outside perimeter of your layout to be your ascending track.

 

Also, one secret to SCARM is using the Gargraves flextrac for all those odd lengths of tracks that standard sizes don't fit.  I'll play around with your file a bit more later when i get some daddy quiet time and see if anything tickles your fancy.

 

Of course your other option is to have a completely separate raised loop that does not connect to the bottom one, so you can run two trains at once.
