hi guys just joined.

i need help with my Hornby track lay out that has not been used for over twenty six years.it is two tracks with four sidings , i got it set up in the past week some of the track has gone rusty so i cleaned it with a bit of wire wool. I have just bought a Hornby control box hm2000 but when i put the trains on the track they go very slowly gradually increasing in speed but don't get up to full speed. I don't want to replace all the track due to the great expense that would be. Just wondered if anyone has got some tips to get it running satisfactually . It is fixed to a board 8ft by 4ft
