David_Sco Good to hear about the spiffy new electric trains. Our trip is in May 2018. Hopefully they'll be fully in service by then.
There are also buses which run at 15 minute intervals during the day between the cities.
Another, cheaper, option.
NEW trains due February (hopefully), if they are in service by then, then the planned journey time is 43 minutes.
Btw, this is a Commuter route, just turn up and go, no need to purchase tickets in advance.
