I have just bought 45114 from my local shop and comparing it with an old mainline I find that there are only two sandboxes per bogie. When checking on the web this is correct from the pictures I have seen of45114 and other 451's. However early 45's (green) had 4 sandboxes per bogies so is D67 incorrect in having only one sandbox.
Why is the NEM coupler pocket at a non-standard height? I had to combine a Kadee with a standard Bachmann coupler to get the Kadee coupler height right.
Why doesn't it pick up on all the big wheels (driven wheels on the real thing)? Not a big problem once I got all the pickups working properly.
Not as powerful as a Heljan 47 up my 1/33 gradient.
Overall a much better model than the old Mainline 45 I have.
