2 questions on railway modelling
 

I've got a small Hornby trainset with a big range of locomotives, including a class 86 in Anglia livery. Due to years of rough treatment (I was pretty young when I got it) the pantograph got so bent and mangled up that I had to take it off. The body of the loco has still got the fittings so does anyone know where or how I could get a new one fitted?

My second question is on track. due to a lack of space, I am having to keep 2 engines on the same siding. I would just get some hornby iscolating track but that is a straight section and my siding is a curve. does anyone know where I could buy a curved iscolating track section that is compatible with standard Hornby track?

Both of these things I could probably improvise without, but they would both be really useful.

Abbiegails and East Kent Models do Hornby spares, but I don't think either have had pantographs for some time. You could always test your modelling skills with the Hurst pantograph kit!

This Sommerfeldt pantograph should be a reasonable replacement for the Class 86.

If you have suitable tools you could make a curved isolating track by cutting through one of the rails and soldering a wire either side.
