Is This Dtg First Steam Train Shot?

I’ve just watched matts three hour brake masterclass. Really good watch. At the very end this caught my eye. I wasn’t sure if this was just a ts 2021 clip or a well hidden teaser.

I don’t have ts2021 to know.....

 

I just had a look and it's gameplay from ts then goes back to a vid of tsw then back to dB br train from ts so not sure it's a hint to anything

 

Looks like TS but congratulations on your perceptiveness BR o7
