Happy Holidays Everyone!  I have a quick question and hopefully there is an easy answer.  My 5 y o Baldwin 2-8-0 Consol. runs fine with the DCC chip.  I have two spots on my layout where the grade is quite steep and the loco cannot quite make the grade--wheels turning furiously when cranked up but there isn't enough traction to make it up the slope.  Any suggestions besides tearing up the layout to decrease the grade? 
Thanks!
Bryan
