How to ballast curved Lego train track

I love the look of ballast and sleepers on Lego train track, it really adds an extra level of detail to any train display. It is however very plate and tile intensive, so it needs to be approached with a budget in mind.
I use either Light Grey, Light Bley, Dark grey and Dark Bley to add to the affect.

Here is how I start out with a curved 2 piece section.

Step 1:Using a mix of eight of the 2x10 Light Grey/Bley and one of the 1x10 Grey/Bley plate, I apply them to the bottom of the track.


Step 2: Add the remaining seven 1x10 Light Grey/Bley plates.



Step 3: Next is the eight 1x4 Light Grey/Bley plates that get held in place with the seven 2x4 and one 2x3  Dark Grey/Bley  plates across the top. Then apply the one 2x4  Dark Grey/Bley  plate , seven 2x3  Dark Grey/Bley  plates and two 1x3  Dark Grey/Bley  plates to the top and bottom right of the section.



Step 4: Now, it's time to turn the plate over and apply some more Light Grey/Bley plate as below. Eight 1x1 Light Grey/Bley plates along the bottom, eight 1x4 Light Grey/Bley plates in the middle section and eight 1x2 Light Grey/Bley plates across the top.
The reason we do this is so that we can apply the sleeper tiles.



Step 5: Now apply the sleepers (sometimes called ties) as shown below which consists of sixteen 1x4 Reddish Brown tiles and thirty two 1x1 Reddish Brown tiles.



Step 6: Additional 1x1 square and round plate can be added to show loose stones if required.
