Unfortunatly you are finding out the hard way why tender drive became so unpopular here in the 90's and why we now insist on loco drive.
I personally dont recommend anyone building gradients steeper than 3% (1:33)
There are 3 possible soloutions.
1. Reduce the incline. which you probably wont want to do as you have already built your layout.
2. Reduce the weight of the coaches. try removing the weights and see if this helps. some coaches (the bachmann mk1's for instance) are quite heavy.
3. Increase the traction on your loco. the hornby traction tyres were pretty poor. try replacing them with roco ones that were made from a different compound and seem to have alot more grip. you could try adding some lead in the top of the tender body.
Let us know how you get on.
