O ran effaith y digwyddiad hwn ar yr economi ehangach, mae’n anodd rhoi amcangyfrif meintiol dibynadwy. Yn amlwg, roedd digwyddiad wedi amharu yn sylweddol ar batrymau gwaith. Er hynny, wrth geisio pennu’r effaith gyffredinol, dylid ystyried y ffaith mai cyfan gymharol fach o gymudwyr sy’n teithio ar y trên, hyd yn oed yn Ne-ddwyrain Cymru, ac y byddai llawer o’r gweithgareddau ar y diwrnod hwnnw wedi’u gohirio yn hytrach na’u canslo’n gyfan gwbl.
In terms of the effect of the incident on the wider economy, it is difficult to provide a reliable quantitative estimate. Clearly there was widespread disruption to work patterns. However, in judging the overall impact, account also needs to be taken of the fact that rail travel accounts for a relatively small share of commuting, even in South East Wales, and that in many cases, activities may have been delayed rather than abandoned altogether.
