As far as I am aware the highlighted numbers were hand painted and this is now done by stencil, transfers , interestingly enough you mention 202 which was involved in mishap with 182 about 1998 /99 this coincided with the restoration of saloon 351 and some of the retired painters were involved in this project and were working on 351 at about the time 202 was being repaired , so possibly they did the highlighted numbers on 202 ????
