Even some of my most powerful Loco’s won’t do well on a 3%.

I would follow Geoff’s suggestion and try experimenting with the grade.
My current layout has ended up having a 1:20 grade which wasn’t working initially because of the tight curve. I modified the curve and now no problems.
Getting your transition start point and radius is the crux to success. I have found that transitions can also need bending the rails on some grades, that is, giving an upward curve as in real life, not dead straight rail as the grade starts.

You can always double the hill———if you want to hall 20 cars ect. you take part of train up the hill and put it on a sideing then go back down and brign the other half up thats called doubleing the the hill

However, the layout is small, so trains will be short and should work. 2% is always recommended ware possible.

Suggest you look into reducing your grade if at all possible

In some places I think with some customizing to make things work, there is a little more than 18. I used to use those Bachmann 85′ budd coach cars and I ended up quitting them. I found some Riverossi shorter coaches that worked better but since I have put on switch system and some new track, I have not tried those cars yet cause I am still working on perfecting my joints. I know that if I tried those coaches, in some places there would be issues. I need to make sure all is good with locomotive only then do cars with it. I have some cars on the track but they are parked in different area til I am ready to try them.

I have used a 3 percent incline on my layout and the curve included is a 24 inch radius, and this works well as I dont usually pull more than 4 passenger coaches. This may not be the case with a 18 inch curve, so yes a test track may be a good idea. If this is not acceptable, then I would investigate the cost and ease of adding the DCC CONCEPTS magnetic power base system. Hope this helps.

https://www.dccconcepts.com/product-category/track-and-track-making-parts/improving-adhesion-and-pickup/

A metal plate under the track and the powerbase magnets in your loco.
I use their magnets for decoupling, too. (1 on either side and under the track with holes cut into the track base to accommodate them)

A lot will depend on the locos you have and the number of cars you will want to pull. With 18″ curves, you’re probably not using monster locos so you’ll probably be ok with at least 8 or 9 cars. Make sure the cars aren’t too heavy – check them against the NMRA standards. (Don’t forget, if you have steam locos, the tender will count as a car unless it has its own drive system.)
