It's okay. Your secret train obsession is safe with us.
Sure, you told everyone you'd grown out of it around your eighth birthday, yet here you are, fascinated to see the next step in locomotive transportation set to transform the nation's capital.
Here it is.
There she is. What a beauty.
Transport for London has shown off the final design of the trains that'll be serving the new Crossrail network.
With space for 1,500 customers in nine fully-interconnected, walk-through carriages, the trains are 200 metres in length.
Set to be constructed in Derby, they'll sport on-train customer information systems with real-time travel information, and more importantly, free Wi-Fi on all trains and platforms.
Due to be completed in late 2018, if you need us, we'll be sating our training longings with a Hornby set.
