James, why are the 160km/h tunnel the same has the 320km/h one?
For some reason, you seem to have posted this query in an unrealated thread, so I have split it. However, I do not understand the question: in what sense is the 160km/h tunnel the same as the 320km/h tunnel?
I think he means they share the same graphics.

That would be because nobody has yet had the time to produce extra graphics for them, I should expect, coupled with the fact that the graphical differences would be subtle in any event. It would be worthwhile to have some difference in graphics to make clear to players that these are separate items, however, so if anyone would like to produce some additional graphics, I should include them (providing that they fit the pakset well).
