Acrylic Question

Wondering how easy it might be to remove a dodgy weathering job (my effort!) from an IRM A class, which used acrylic paint?  It's along the bottom of the loco body so a flat surface at least!

TIA

Very gentle rubbing with a damp cotton bud (damp with IPA )might help

Try applying the same acrylic paint to a piece of scrap plastic and then test your method on that first. 
The IRM paint is moderately resistant to solvents but the lettering (loco numbers etc) comes off very easily with IPA, thinners, white spirit etc. Be prepared to lose those.

You could try washing up liquid and hot water, it should come off if you rub it with you finger nail.

Anything more could mark the surface and avoid the numbers/lining. Do you have a picture of the loco?

Not a great photo but gives an idea:

It doesn’t look too bad in the photo, but up close it looks very amateurish to me, particularly on the flat bodysides, so I’ll have a go at removing it.  I’m shortly going to move this locomotive on, so I want it to be very presentable for the new owner!

In that case I'd second the suggestion of starting off with water and washing up liquid. IPA can go badly wrong so if you go that route start of with strongly diluting it. You might use tooth picks to get the paint from crevices. 

I would separate the body and work on that even more gently. You can be more aggressive on the plain black plastic but still beware of solvents as they can sort of bleach plastic and make it look washed out, even if it's unpainted.

I don’t think you have much hope of getting it back to ‘very presentable’ condition for sale. Almost any method that removes the acrylic paint will leave some degree of damage to the surface below. OK for weathering over again, but it won’t look factory-new.

No hope of getting the bogies cleaned but but I'll take Philip's advice and take the body off and work on that, so I can keep any cleaning liquids well away from the sensitive internals......

Remove the magnetic roof panel then unscrew the screws holding the body to the main chassis block. Get some cocktail sticks or plectrums between the bottom edge of the body and the chassis block. Be careful of the small pipework details at the bottom of the bodyside. 
the body should then pull off vertically.

Using plectrums might cause me to fret

You should apply for a job as Accurascale's chief pun generator! 

Their latest Mary Poppins themed effort is extremely tenuous...

I’m sure you would be well tuned to their requirements. You might even strike a chord with the customer base.
