The Western Force will consider taking a train to Melbourne for Friday night's Super Rugby clash with the Rebels if their flight to the Victorian capital is cancelled.

The Force's scheduled flight to Melbourne on Thursday morning is in danger of being postponed, as more volcanic ash makes its way into Australia's airspace.

Force coach Richard Graham said the Perth-based franchise were considering several contingency plans, one of which involved catching a train to Adelaide and then flying to Melbourne from there, or catching a train direct to Melbourne.

"We'll walk," Graham said with a laugh when asked what other options were left.

"No seriously, we're keen to get there, so if we have to get the train overnight and fly from Adelaide, we're exploring everything because we're very keen to get there and play on Friday night.

"At the end of the day, we want to finish the season well and sitting here in Perth isn't going to give us the opportunity to do that."

Graham said the Force weren't interested in calling the game a draw, and would also consider flying to Melbourne on Friday morning if all flights were cancelled on Thursday.
