Barry to Llandrindod Wells train

[Captain Kernow]

In the John Hodge Barry Railway book, there is a reference to a GWR service that ran in the 1930s from Barry to Llandrindod Wells, running via Merthyr.

 

Whilst I understand the route the train would take from Barry as far as Merthyr, I am a bit puzzled as to which way it would have gone after that.

 

Would it have run north from Merthyr to Three Cocks Jct and thence to Builth Road and make an awkward shunt from the Low Level station to the LMS line via the connecting line?

 

Or would it have taken the other route at Three Cocks and proceeded to Hereford and then north to Craven Arms, reverse and then down to Llandrindod Wells?

 

Many thanks.
