Cakeday Giveaways [Over - Solution Added]

Some of you might remember me from this thread about the attitude of people who have a negative history here on the SteamGifts. Don't worry, this thread is nothing like that.

Apparently today is my cakeday! I've never really understood why people give away games on their cake days but, hell with it! In keeping with how I do these, I have hidden a train I hope you will enjoy within this thread see my last thread to get an idea of how I do these.

All GA's are a minimum of level 1, with some going up to 4, and last until 11:59pm (UTC) October 21. You can get to the train with minimal puzzle solving skills.

Enjoy!

=================== Two days left edit:

There are only 2 days left and these GAs have as few as 10 people. I won't change the way the puzzle works, but strongly suggest you read everything I have posted as a hint in this thread:

• 2nd paragraph of this post
• 1st post in the thread
• Hint
• These posts
• And because I'm nice here's a new hint. Everything you need to enter the train can be found in the OP and first post of this thread.

=================== It's over!

For those still wondering how to get to the Train, you needed to look into the HTML of the OP, where you would find 4/5 characters for the GA hidden.
After that, the 5th is in the first comment in the thread. Congrats to the winners!
