Trains parked/shunted far from end of platform at Heuston

[cherryville]

'Would they re-fuel the van whilst at the platfrom?'

Yes they do.

'Is that what those things with the long hosepipes are for between the tracks in Heuston?'

The hosepipes between the tracks are for retention tanks (mk3a for example) and for filling toilet tanks and dining cars.

There are extra hosepipes located at the cork end of the platforms for fuelling the vans. They are located where a van on a 9 piece Mk3 set would be.
When a van on a shorter train needs to be fuelled it has to be moved to reach the fuel pipe.

'The vans are nearly always at the Cork end refueling is not done at the platform.'

OK so when are the vans refulled ???
