Looking at the database we appear not to have found any working numbers for TheTrainLine.com.

I have removed 01925 422280 from the unverified database as it's NU.

0131 4441136 is supposed to be a fax number but rings no answer.

01925 671732 apparently goes through to India who give out the 0870 number

What is the number for? What company? Their address? Where did you find the number?

A quick Google suggests this is for TheTrainLine, although maybe for help with the sites they run on behalf of train operators. Is that what you are looking for? Have you tried the TrainLine numbers in the database to see if they can deal with your queries on those numbers?

01925 671732 (maybe payment investigations)
01925 671729 (database says Trainline support for First Scotrail, but as it's a Warrington number, it's obviously not in Scotland, so may be for all operators)

trainline       0871 244 1545             01709 849452            

Just called this number and it totally worked, and very quickly too.

ETA: Fix spelling

Just been trying to contact the Trainline to find out about a reservation today and tried the 01709 849299 number.

Got a strange message about "Due to the circumstances, we cannot take your call at this time", then tried the 0871 number and it went straight through. So not sure if they're blocking the 01709 number or what.
