Perhaps a ticket mentioning "Thameslink" is valid only on the
Thameslink service?


We've been though that. The price is the same [at Bedford] for "London
Terminals", so the potential route-excess is zero.

And it's neither a "Thameslink only" nor a "Not EMR" ticket.

*However* as a bonus, on Thameslink services you can use the ticket as
far as LondonBridge/Elephant&Castle, not only to SPILL.
