However, if they don't have a blocking system that allows for 2-train operations that sucks anyway...
To be fair, when Booster Bike was built the park didn't really need it to have the ability to run two trains. Buying a second train and/or having a system that allows for two trains was just an unnecessary expense.
I guess it's not out of question to retrospectively add appropriate blocks, but that's probably quite expensive and a lot of hassle.
