Planting small Dioramas on the line can be a difficult procedure but I, as a keen Bonsai creator and grower, have devised this method. By planting the diorama in a small container first ( here I have used a bonsai container but a seed-tray would do just as well ) you have full control of the planting which can be left for a few months to mature.

When mature, all roots will have knitted together to form one large mat and then the diorama can be lifted out in one piece and planted on the line where needed. It works especially well for those difficult to reach places.

This one was created using a home made stile and a few small Cotoneaster and Lonicera plants, struck simply from cuttings, a bit of moss. Simple pruning will keep it all in scale in future.

The ubiquitous coffee stirrer strikes again to provide this simple central heating radiator to go into the station building.  (Quite what a radiator is doing there, with no concept of a boiler, is pure artistic licence!).  A few coffee stirrer sticks separated by Hama beads (or something similar) and held together top and bottom by a section of cotton-bud-stick, plus, at the bottom by a short length of mains copper wire, which obliges with providing the plumbing too.

Looking to add a bit of interest to the interior of the Station building (a Brandbright kit) I've used a discarded non-working wristwatch as a clock. 

Extra tip - if you use more than one, set the time consistently first!
