Train Conductor World: European Railway guide - How to prevent train wrecks and wrack up a high score

Train Conductor World: European Railway is a fun and colorful puzzle game that challenges you to redirect trains to their correct paths while avoiding accidents - all in the name of a high score!
To help you, we've put together a few tips to help you prevent those trainwrecks.
Don't be afraid to stop trainsAn important point to note is that stopping trains is preferable to a train wreck - even though you might not guide as many trains to their destinations or earn as many stars.
Wrecks immediately end a run unless you watch a video, and it harms your ability to earn a high score.
To stop a train, all you have to do is tap on it and it will stop right in its tracks. Tap on it again and it will move.
If you're feeling sneaky and want to slow down trains without losing stars, you can drag your finger across the screen as if to draw a new path for the train.
For as long as your finger is held down, the train will move a little bit slower than normal, which might be exactly what you need to avoid an accident.
There's a temptation with games like Train Conductor World: European Railway to try and draw the quickest and most direct path for each and every train as soon as it comes on screen. If you are able to pull that off, great! But don't get trapped in the mindset that you need to do this to succeed.
Sometimes, having patience and timing your trains to divert onto alternate paths is exactly what you need to space trains out so they don't collide.
Heck, if you need to, you can redirect trains to the wrong paths before setting them back on the right ones. The idea here is, there is no right or wrong way to direct your trains - so long as they end up in the right place once they get to the opposite end of the screen.
