Look like President Choice train model series,but this model have potential..
for light bulb,it's very easy to replace
Wath we can do for this kind of model to make it more attractive..
remove the shell and paint it..all in black,just need to preserve grey part and road numbers with masking tape..
Paint the roof in black instead of red or leave it like this can be an option,it's not neccessary to paint it,but it depend of the project..
painting the green part on the frame with a small brush..
then we could put real kadee's in the front and back,if the tender are green,*that could be possible) we can paint it in black,add roadname on it.
overall,convert it in DCC,could be a pretty nice model to do a steam locomotive to move coal cars,in a little company.
