Is it worth it to save the extra money to use this from Heathrow

Alternative oyster single fares:

No, I don't think so. Unless you really want an excuse to go via a

(Also, note that not all trains to Tilbury stop at Upminster during
peak periods.)

I got the schedules they leave every half hour during the 11 am to 1
