Travelling in to London with a buggy

[Subeccoo]

Hi all,
Has anyone got the elizabeth line from Shenfield to Stratford with a buggy?
What would be the best way to get from any of the A12 stops, ie gants Hill, Romford etc with a baby in tow?

Should have put an AIBU
AIBU to think I can get the elizabeth line from Shenfield and park there no problem given that I've never done it before 🤔
