[*]We cannot carry tandem's, tricycles or bicycle trailers on any of our services. We simply don’t have room – sorry!
BUT
atob.org suggets tandems *are *permitted (and also for firstcapitalconnect (Kings X - Cambrige), which isn't contraindicated on fcc's website).
But if you dig around a bit, NXEA's site also has this to say:
Can I carry tandem's, tricycles, cycle trailers or double deck cycles on your trains?
**Cycle carriage information**
Tandems may still be carried on our mainline rolling stock (the loco-hauled Norwich – London intercity services, the former Great Eastern emus and Class 170 style trains*.
Unfortunately we cannot carry, bicycle trailers, double deck cycles on any of our services. We simply don’t have room – sorry!
