Streamlined Steam Locomotive.
Built on inspiration of Ben Fleskes fine work.
Big Ben Wheels are used for the entire locomotive.
Please notice the front wheel cowel made of minifig seats turned upside down.
This is Bens brilliant idea.

Small power funcrion motor used, it consumes less power giving the locomotive
about 5 hours running time with 2 coaches added.
However the small motor gets very warm after a couple of hours,
but given a 15 minute break, it's ready to go again.
My test was made without the 8884 IR control, using the 8878 rechargeable battery.
