+1 for everything said by
@lock4244 - the CN SD40U, SD40-3 and a non-db SD40 would be great, although I'd appreciate a SW1200RS (and a CN GS-413, aka SWEEP) to fit the LL mech as that's what I have stashed away.
More of the Canadian stuff please,
@davidmbedard - and if you'd be so kind as to point the shrink ray towards your excellent range of CP vans...
