I think this looks nice, isn't it?
Fill inbetween tracks with some foam polystyrene to make it lighter.
Put some waterbond then color powder. Then again waterbond by a syringe to glue the powder better.
Put some balast to hide the rail edge as it was outstanding than I supposed.
Touch the balast slightly by a brush to make it flatter and calmer by lightening there. Later pour some waterbond there to glue it better. My far sighted eyes hurt!!!
