Obviously these additional services require extra money but one wonders is the IÉ to NTA application to operate them of a:
(i) mere request to operate additional trains nature
(ii) request to operate additional trains including a request for funding of same nature
A request of type (ii) may not necessarily be the case; perhaps IÉ can somehow obtain the requisite money/ balance it against savings elsewhere.
A request of type (i) is highly likely to succeed , a request of type (ii) is likely to be a bit harder.
(labels (i) and (ii) assigned for convenience of discussion and no importance attaches to them otherwise)
