Sudrian Industries' Island of Sodor Project - Missing DLC Assets

[FlowersMeLikie]

There are some assets that are required by the map mentioned in the title, but I'm unsure of what DLC the payware ones are from, nor where to get the unknown one.
Is anyone able to help me out?
Their IDs are:
<kuid2:84609:28430:1>
<kuid2:84609:28414:1>
<kuid:240029:100094>
<kuid2:84609:28416:1>
<kuid2:283523:22050:1>
<kuid2:35412:28261:1>
