I don't think much is moving around Yeovil Pen Mill at the moment
Yikes!
and yet ... the disruption lasted only two hours. One
GWR▸ train from Weymouth was an hour late, two going there were cancelled "due to severe flooding (X2)", and an
SWR» train to Westbury was also cancelled, but "due to flooding (JK)". Obviously SWR use a different dipstick. After then one return service from Weymouth was lost too, but that was it. I guess that's typical of flash flooding.
