Railway Track is an expert difficulty track (featured only as a regular track on iPod/iPhone) in Bloons TD 4 and Bloons TD 5 Deluxe.

Bloons TD 4Edit

In Bloons Tower Defense 4, it is a premium track that costs 15 NK Coins to buy it. The bloons come up from the top and eventually merge into one track at the bottom. There is water on either side of the track at the bottom for Monkey Buccaneers. This track is arguably one of the hardest in BTD4 because it has so many entrances and it is very difficult to secure them all especially considering the shortness of the paths. 

Bloons TD 5 DeluxeEdit

The track is also featured on Bloons Tower Defense 5 Deluxe and is unlocked at Rank 29. The paths are a lot longer than they used to be as well as the fact that you have a much larger variety of towers and upgrades comparing it to BTD4, making it much easier in BTD5D. Despite this, it can still be quite challenging managing all of the paths like in BTD4. The track has also changed dramatically in visual appearance, making it look more realistic compared to BTD4 as well.

Tips and StrategiesEdit

• The center part of the track seems to be an ideal place to put Boomerang Throwers and Tack Shooters on.
• A Spike Factory would help heaps on this track since it only has a single exit unlike most multi-path tracks.

TriviaEdit

• There is water at the sides of the track down the bottom.
• This is a premium track in BTD4 and Bloons TD 4 Expansion, but in BTD4 iOS and Bloons Tower Defense 5 Deluxe, it is not.
