Rocky Trains

[Mark Gleeson]

201 is outside spec on track forces
The track laid was designed for 90mph with a 99 ton locomotive not a 100 mph 118 ton one
The new Mk4 coaches are each 5 tons heavier than the Mk3
The Mk4 should have higher track forces than the Mk3
The service frequency on the Cork line has effectively tripled in 10 years
More trains run making fewer stops, more track wear

It all adds up to serious track problems. Even the trusty Mk3 can have problems. The Mk4 suspension could be better but its unlikely to significantly change matters unless track is also fixed.
