Sounds like we have a lot of building experiences in common. Most of the
obstacles to large scale train modelling are familiar to me, since I’ve been
working on GMLTC’s 8-wide layout for the past five years or so. We found that
the weakness of Lego’s magnets can be overcome by adding some of strong wafer
magnets in between their couplers. We’re lucky in that a local store chain
called Target has been selling them dirt cheap lately. During the last
outing of the GMLTC I was present at, we ran a train with two locomotives (2
motors each) hauling 13 8-wide freight cars (for a train almost 20 feet in
total length) for about 5 hours before having to give the motors a rest.
GMLTC’s layout has a grade of 1 plate per 16 studs through most of it, so
that’s quite a workout for those tiny motors!
By the way... I like the buildings in the lower portion of this picture:

The buildings are a Blacksmith’s forge kit and another one built as a mirror
image! This is the old trick of using a decent kit to fill in a gap. I did the
same with wagons - notice the 6 Octan tankers in the middle, just in front of
the gasholder, as well as he digger on the left. I also modified a few of the
newer Octan tankers to make them 4-wheelers with sprung pivoting wheelsets. The
existing use of kits is one reason why I’m rebuilding to enhance the scenery.
The track slopes for my new layout are 1 plate in 16 studs (1 in 40) on the
curves (probably the maximum to avoid derailments), with up to 1 plate per 12
studs (1 in 30) on the straight (4 plates per 48 stud module), in order to rise
far enough in half a circuit to get a train over another train with a 48-plate
height difference. I set the maximum slope at 1 in 30 since that’s in the
region of the maximum slope on the real railway.
The 48 plate height difference leaves about 37 plates height under a bridge, a
scale dimension I brought over from model railway books. I made the slope half
a plate in 16 studs for the change of slope from level to 1 plate per piece.
This uses SNOT technic beams on jumper plates. The more gentle change of slope
should avoid wheels rising off the rails and motors racing on the hump.
Was that 5 hours of crawling with the long train?
