As long as UI'm cluttering up the place with 0n30 stuff I thought I would post a pic of my engine house.You may recognise the building as the Bachmann Car Shop but with a little work this HO building makes a credible O scale engine house.
This not the finished product but a construction shot (I can't find the finished building pics

)The trusses you can see through the skylite openings are all scratchbuilt from Evergreen shapes as there are not enough in the stock kit.Other than the trusses the only changes made (to convert from HO to O) were the front doors and a new foundation to raise the building to the proper height.Oh yeah,and a O scale sized people door on the right side.I may change the roof to a modern shingle style since my railroad is set in the current timeframe.
