The EU07 has a few things that should help.
 
First it has a 'Current Setting' switch ... it's one of the 3 rotary switches on the middle of the console, the right most one.
It has 2 positions, normally it's in 'Low Power Mode' this is for normal driving,
But if you turn that switch to 'High Power Mode' then it allows upto 750 amps instead of 600 to the motors in the serial notches ... i.e. the first 28 power settings,  
This is switch is be used to help get a heavy freight train going,
You need to put the switch back to low power mode before moving into the parallel motor notches... notch 29 upwards... if left in high power mode the motors wont switch to parallel and you'll go no faster.
 
Then there's a rotary switch 'Adjust Forces To Wheel Pressure'  i am not sure about that one to be honest,  thought it may be something like traction control in  a car,  you can hear a nice thunk from the electrical room when it's operated, but can't say i've noticed it do anything.
 
There is a green mushroom button to the left of the power wheel called 'Antislipping Brake' 
You press this when the wheels are slipping, and it rapidly applies some braking force to the loco wheels, much faster than the loco brake lever can apply and release the brakes... so it's sort of a manual ABS system.
 
Others have said, if the trains not rolling back down the gradient, then you haven't fully released the brakes,  it takes a while to release all the brakes on a long cargo train, so putting the train brake lever to the fill position can help get them off a little faster (just remember to put the lever back to running, as over time if left in fill it can overcharge the brakes)
There's also the 'Brake Releaser' button you an use to help release the brakes fully... a green mushroom button to the right of the power selector rotary switch.
 
As for sanding... i believe this should be operated with one of the foot controls, but they do not move yet, there is a 'Sanding Breaker' with the other breakers below the flap in the desk that battery switch is in... thats on by default tho.
 

the right hand gauge isnt reading where it should... it looks to be way over at 1.6Mpa,  that's the main pressure i believe, it shouldn't go over the red line at about 0.8Mpa.

Not sure how you'd correct that... the safety valves on the compressor and tanks should have operated a little above 1Mpa or so,

:

i had accidentally turned the compressor off once flipping switches, forgot you have to press the 'compressor overload release' button to start the compressor back up, but that results in the brakes not being able to be released as the main pressure drops, right hand needle went down to about 0.5Mpa when i noticed this... but i could also tell the brakes were not releasing by left hand gauge not going back to zero,

 

I've just chosen the EN96, i was on the English Beginners server at about 18:35... unfortunately all i got to do was sit at a red light with about 7 other drivers on other tracks,   apparently the previous dispatcher routed a few trains onto wrong tracks deliberately then left... that's what i picked up from the radio chatter.
