Place a cross track and rotate the turntable to place another one and try eyeballa a triangle like in the image, repeat this step for as many engine shed you want/can fit

Place 14 meters of bridge in the end of the crosstrack and then place 22-25 meters of bridge in the end of the 14 meter bridge as seen in the second image and repeat until every crosstrack is done

Delete the 14 metre bridges

Place 3 cross tracks on the end of the 22-25 metre bridge

Place trestle bridge sections, longer then the middle bridge section, like on the image and repeat for all of the bridge sections until you have populated all placed section sides like on the ex image 2

Use the mouse and WASD keys to align the engine house to the middle bridge section

Use the WASD keys to get the right alignment and height of engine shed, the track should be a bit in the front board of the middle bridge or a bit above like in the red circles

Delete the trestle pieces and use the front board of the bridge to align ground works then eye ball the ground work to the corner of the shed and place it, result in the last image (you might have to delete one trestle from the next shed to place the ground work), later use same method to do the other engine shed in the front and side and back you can eye ball as you are finished

Rotate roundtable to be like in the image 1 and place the first track, look at the image 2 and see how to place the second track, repeat for other sheds

Aim about where im aiming and delete anything crosstracks and anything else what is not needed anymore
