Describe the issue

A while ago the option to reverse any coaster train was added. However, the game had a few of those as separate trains, such as the heartline twister cars (reversed) and the 6-seater wooden coaster (reversed). Those train types were removed since they're now unnecessary, but that does mean that saved designs that use a reverse train, such as both Heartline prebuilts, should have this option enabled when build, which currently does not happen.

So far I know of the following designs that use reverse trains

• Twicky Twister (heartline) - RCT2
• Big Twister (heartline) - RCT2
• Heartline Twister 1 (heartline) - RCT1
• u(5830) (looping coaster) - RCT1

Steps to reproduce

1. In both v0.4.8 and v0.4.9 create a park with all heartline trains enabled
2. Build a Twicky Twister prebuilt in both of them.
3. Observe the difference in which ways the trains are facing. 0.4.8 is correct, and 0.4.9 is incorrect.
4. If you create a park in 0.4.8 or earlier with the reverse trains selected and import that in a newer version, it will work as then a compatibility object will be selected.

Start by tracing how saved prebuilt designs select vehicle types and how the reverse option is applied during construction. Reproduce the listed heartline and looping coaster designs in the affected versions, then verify that each design builds with the same reversed train orientation as before the separate reversed vehicle types were removed.
