The group said road transport and warehousing operations experienced 'reasonably static' revenues compared to the prior year despite difficult weather conditions at the start of January.Port operations have remained steady and pre-tax profit will show a significant improvement though like-for-like revenue will be slightly lower.Stobart said rail operations are performing very well with the freight services growing through the recently commenced Valencia chilled service. The rail civil engineering operations are performing well above forecasts. Overall, it is expected that rail will be significantly ahead of the prior year, the group added.The Airport operations are in line with management expectations.
