Many thanks Gents, the train length is 10 x FLA's with 20 x 40' Hi Cube containers.
I have run the consist with an additional 2 x FLA 's (4 x 40' Hi Cube containers), but the locos seem to struggle mainly due to the incline up the viaduct. We tried 13 x FLA's i.e. 26 x 40' Hi Cube containers but the consist pulled itself off the curves, due to the physics involved given the small diameter of the wheels.
The video was an example, prior to dabbing the glue onto the container and Lubricating the axles, it was impossible to get more than 8 x FLA's (16 x 40' Hi Cube containers) to run without de-railing or the containers falling off.
The Maersk wagon is hobbling probably because of my poor adhesive skills!
Great wagons though Arran!
Apologies for any confusion.
Best, Chris
