Ugh. Chiltern are making a mess of this. They've published timetables for Monday. However, they don't jive with what the instructions on the engineering work summary says. The summary says to take FGW to Oxford and join the Chiltern services there. However, the posted timetable for Easter Monday doesn't have any Chiltern services from Oxford. (The one for Easter Sunday, however, does.) Do I need to call Chiltern about this? National Rail Enquiries is routing Oxford to Stratford-upon-Avon that day using XC to LMS and then Chiltern. Chiltern says nothing about anyone other than FGW accepting their tickets, but I have no freakin' clue how I should get from Oxford to anywhere using Chiltern on Monday. Hoping someone can help me out here.

Thanks!
