			=== Middle Brake Beam ==

			The Middle Brake Beam should be 2-1/16 inches wide, not 2.75 inches, to accommodate the above changes. See 3d model for details.

			=== Drain Cocks ===

			There were two issues here. First the handle on the tapered plug and the handle on the shaft must have the same distance between centers – use 1/4 inch. Second, the shape of the connecting rod had to be altered to let the shaft go through the approximate location in the bogie given without hitting and screws (almost flipped its profile) – the hole in the connecting rod should probably be slotted. See 3d model for details.

			=== Bogie ===

			By lowering the connecting rod shaft for the drain cocks you need to put a clearance cut in the bogie bolster. See 3d model for details.

			=== Boiler ===

			There are a number of issues here but the biggest is the vertical pitch of the firetubes. It really must be 3/8 inch (not 7/16 BARE). This will setup the upper features correctly.

			=== Backhead ===

			[[File:Doris Backhead Correction.png\|thumb\|center\|500px\|The 5/16-40 tapped holes in the backhead should be at 1.25 inch not 1-3/16 inch from the top.]]

			=== Regulator Lever ===

			[[File:Doris Regulator Lever Correction.png\|thumb\|center\|500px\|The center regulator lever needs to have its lower 7/16 inch dimension changed to 3/8 inch.]]
