WIP Lego LNER 4472 Flying Scotsman Steam Locomotive

[jamesed_1971]

Hi, on Friday 7th Feburary, my Big Ben Brick wheels package arrived, I started to build my new motorized chassis for my new version of Lego LNER 4472 Flying Scotsman Steam Locomotive using the XL flanged drivers and the XL blind drivers and the small flanged train wheels, it took me a couple of hours of finding the parts and building the model

The reason the are two Lego Power Function Cables is the one on the left is the extension for the rear lights which are to be installed in the rebuilt LNER Flying Scotsman tender, while the other cable is from the IR Sensor.

Saturday Morning I did the first running test, on the old Lego blue 4.5 Volt Train Track, the train ran OK, then I did the second test, adding some curves to the Lego track, when the train came to the curved part of the lego track, it either stalled or derailed.

I found where the problem was, there wasn't enough clearance between the steam cylinders ( 2 x Lego Technic Cross Blocks 3M ) and the leading bogie, I rebuilt the front section and put the steam cylinders higher, with the result the leading bogie has plenty of clearance.

I did the the second test, and the train can move around the curved section of track.

the tender base is still being built.

UPDATE

I have made a virtual model of what the model will look like when finished in LDD 4, exported as a LDraw file, edited in MLCad, added the XL Wheels and flanged train wheels, opened in LView to take some snapshots of the model.

The tender seems a little basic. The wheels and underframe just dont look right. But the loco looks nice.
