Oyster has arrived in Brentwood, if you ignore the fact that it arrived on the 498 bus ages ago! It's now here on the trains too. The fares aren't quite as simple as they could be, so we've prepared this table to make it clear how much a journey into Greater London will cost using paper tickets or Oyster:
The surprising fact is that some day Travelcards are cheaper with paper tickets than on Oyster. Oyster's only the best deal if you'll be travelling into London on a train that arrives at Liverpool Street between 1000 and 1200. For single journeys into and out of Greater London, Oyster always works out cheaper.
Watch out for the £16.20 off-peak pay-as-you-go daily Oyster fare cap when travelling from Brentwood though - it's quite high and can only be avoided by either using a paper ticket to travel from Brentwood into Greater London and then switching to Oyster or by using two separate Oyster cards, one to get over the border and one to get around London.
Here's how the paper v Oyster fares look from Shenfield:
It's not yet clear what situation is regarding the Brentwood & Shenfield Plusbus, but my guess is that it is not available in conjunction with Oyster.
