Garden Railway Forum

I started to modify the layout and I did the new departure from the actual layout to the extension.

I used water resistant pine deck board assembled with galvanized pate:



I had to open the acutal delimitation of the layout :





Here is a quick video to validate the new added part :

The extension is now fully operational for test :


I need to adjust the support of the loop. And after there will be a lot of landscaping work to do.

That's really great. Not so Sam Small now ........

That really is lovely Sam. I can't believe the difference! Well done.

Yes that's much better. I have to find plants that can grow under the thuya now...

BTW, make sure you treat the cut ends of your boards with wood preservative. I didn't with my first raise timber section and paid the price a few years later.

I'm no horticultural expert, but Thuya's are conifers I believe. Finding plants to grow underneath them is going to be a major challenge please let us know how you get on.

This came from an AI bot when asked the question "underplantings of Thuya"
Hope it is of some help

Underplanting Thuja (Arborvitae) can enhance the garden's aesthetics and provide year-round interest. Consider ornamental grasses, flowering shrubs, or spring bulbs for varied texture and color. When choosing underplantings, consider the specific needs of Thuja, which can benefit from companion plants that repel pests or provide visual contrast.
Elaboration:
1. Thuja's Needs:

Thuja (Arborvitae) thrives in well-drained soil and full to partial shade, so choose underplantings that can tolerate similar conditions.

It's best to avoid dense planting that could compete with the Thuja for resources.
Consider the long-term growth of both the Thuja and underplantings to ensure they don't become overcrowded.

2. Companion Plant Ideas:

Ornamental Grasses: These add texture and movement, like Hakone Grass or Blue Fescue.

Flowering Shrubs: Hydrangeas, rhododendrons, and azaleas offer color and contrast.
Spring Bulbs: Crocus and grape hyacinths provide early-season color.
Shade-Tolerant Ground Covers: Ajuga, Vinca Minor (Periwinkle), and Lamium (Dead Nettle) can thrive in the shade under Thuja.
Perennials: Consider hardy perennials like Russian sage or anise-hyssop for late-season color.

3. Pest Control:

Some companion plants, like native lavender or bee balm, can deter pests and improve overall garden health.

4. Considerations:

Light: Thuja is relatively shade-tolerant, but some underplantings may need more light.

Soil: Ensure the soil is well-drained and fertile.
Space: Allow sufficient space for both the Thuja and underplantings to grow.
Maintenance: Consider the maintenance requirements of the underplantings, such as pruning or deadheading.

I thought about low growing Juinpers and found these recomendations.

Several types of juniper ground covers can thrive beneath thuja trees in Europe.
Specifically,
Juniperus horizontalis 'Andorra Compact' and Juniperus squamata 'Holger' are good options, known for their low-maintenance, adaptability to various soil conditions, and ability to thrive in partial shade, according to Gardenia.net and Gardens4You.ie. Juniperus x Media 'Gold Coast' is another popular choice, noted for its yellowish-green foliage, according to Garden Plants Online.
Here's a more detailed look at these options:

Juniperus horizontalis 'Andorra Compact': This creeping juniper is compact, dense, and fine-textured, making it suitable for rockeries and small spaces.
Juniperus squamata 'Holger': Known for its winter hardiness and ability to thrive in all soil types, it provides year-round greenery and can tolerate partial shade.
Juniperus x Media 'Gold Coast': This ground cover conifer offers a unique yellowish-green foliage color.

Today we had good weather in Paris so I started landscaping on the extension around the first S.

Some old bricks to maintain the soil around the rails, and 3 plants are now installer.

I worked on the futur engine shed area :

First step was to print in PETG a turn table found on thingiverse :
https://www.thingiverse.com/thing:4540300



As the bridge is very tight for 45mm I glued directly the rails on it and I also added bearings under the bridge





I designed some supports for the outside rails and glued them on the outside of the bridge







Finally I installed the whole on the railway





The 2 lines will go to the engine shed (need to make the building now) and the bellow line will go to the futur water tank

And finally a quick video to show the first test run :

That all looks great, Sam. Well done.
