Alex;
OMG that station is fantastic! You are the MASTER as always.
I sure hope you have plenty of space for it!
If you are building it for a client, he will need a pickup truck to take it home........
The first building I cut up I used a couple of different hand saws, including a hack saw. It worked, but its hard to stay on a straight line.
The rest I wound up cutting apart using a table saw with a fine tooth scroll type blade. This made nice straight cuts using either the square or the rip fence.
For building comprised of two pieces, such as the country house, I separated them first and cut each main piece separately. Worked OK.
For squarish buildings like the hardware, I cut pieces including about 2" of the sidewalls and roof. The rest of the sides wind up as scrap.
I usually try to avoid cutting through any windows, as they would be hard to reassemble in small pieces. On MTH buildings the windows are easily removable, so you could cut one separately using a fine coping or jewellers saw if you had to I suppose.
The town house and row house series should be easy to work with but I never tried any of these.
I looked at splitting one of the farm house series, but decided the roof and porch does not lend itself to the task at all.
It looks like the storefront types (like the Zangs hotel or the dry goods) would be easy enough to do. You would wind up with a front that is only half as deep, and the back which would look OK as a small boarding house, including the stairway to the upper story. I have not done one of these, yet! Never say never.
It also looks like the 3 story buildings (such as Dewey Cheatum and Howe) would be doable, but again I have not tried one yet.
