Congrats on getting to level 25! I've taken a look at your account and it seems like you are able to expand to the Train Station.
Please hit expand and hit the train station so that you can expand under it. From there, you will be able to repair your train station and start making train deliveries! I've also taken a look at your Lemon Trees. You've received 2 to plant and you can get them when going into your Market. Sometimes, when there are a bunch of animations or applications running in the background, you may not get the popup saying that you've gotten to Level 25 but you did receive the benefits for it. Let me know if you have any questions!
