Talk:Birmingham International railway station

Abbreviations
The list of services uses "tph" (which I presume means trains per hour) but this seems a bit needless and likely to confuse people. I can't imagine a tourist who doesn't speak English as a native language understanding that. Is there any particular reason for this, before I change it to "trains per hour"?
