London Underground D78 Subsurface Stock
About this creation
Mind the Gap!

This is my D78ss train. It is the second of my three LU creations and the second one to be functionally complete (the first still isn’t).

The D78 stock (or just ‘D stock’) runs solely on the District line and numbers 75 6-car trains. It is subsurface rather than tube stock; this means that it in larger tunnels closer to the surface and on open-air routes. The ‘D’ means it was subsurface stock (and coincidentally intended for the District line) which is lettered alpabetically by class and ‘78’ represents the planned in-service year. the Ds entered service in 1980 replacing O, P and R stock on the line. D stock is currently undergoing a very long drawn-out refurbishment programme.

The D stock is arranged into DM-T-UNDM or DM-T-DM (Driving Motor car - Trailer Car - Uncoupling Non Driving Motor car) 3-car units. Two of these units are arranged back to back into one train. When the A stock on the East London line was withdrawn for refurbishment in the mid ‘80s D stock DM-T-DM units were used on that line as single unit trains. My D stock train is in the latter configuration. Just like the actual units my one is semi-permanently coupled with magnetic couplings at the cab ends only.

This train was much easier to build compared to my 95ts and battery locomotive as they were built to the tube standard whereas subsurface stock is closer to mainline rail dimensions. Thus I was able to use ordinary wheelsets and not have to cut the motor into the body.

I have modified this train somewhat; when first built it was a two car train. I built windows in the car ends which actually only appear on the single D stock train that has had the full refit (identifiable by being in the corporate colours; red, white and blue) my train is not that one so I had to remove them. When I came to built a trailer car to go in the middle I also changed from using trans-clear bricks on the side windows to trans-clear 1x2x2 panels. The last work I undertook was to fit a floor inside and add some seats and passengers.

Note to Alastair: I know about the door thing. I had to cut the number of doors and windows in order to reduce the length to make it compatable with Lego track geometry.

Note to Colin: I will not be doing a refurb version of D stock due to parts availability in those colours. I have looked at C stock but its' angled sides make it and A stock impossible at this scale. I believe Mark Bellis is looking at doing A stock in Lego at a larger scale.

Quoting Daniel Walker Great! Just one prob. The D stock has 4 passenger doors on each side, in each coach, in each unit. This has 3.
See the second to last paragraph above.

I think this is the best lego tube that I have seen.I think that this is also better than the tube that is in lego land.
