Class 20 Unterschiede zwischen JT und DTG-Version

I have both versions, the JT version is the better model has more functionality (it is part of their advanced range), comes with the nuclear flask wagons and the water jet wagons which clean leaves from the rails. These are functional and can be controlled from the engine. I have the AP sound pack which works with both versions. As always support from JT is far superior to DTG. You also get several different liveries with the JT version.
