Hi Dave,
Some people have found more luck getting a GPS signal in the
carriage ends (I believe they're called the vestibules?) - however
it's a pretty uncomfortable journey stood their the entire time.
Yes it called a vestibule.
Otherwise, it simply depends on the type of train (some are more
shielded than others), and, I guess, the type of GPS device (ones
with bigger aerials might cope better). Also, I think it helps if
you get a GPS fix before getting on the train - they seem to have
more difficulty getting a fix when moving at high speed (or at least
mine does).
I've found that the GPS you use can make a huge difference in the
signal they can get.
Where are you mapping? Most of the UK train lines should already be
fairly well mapped.
There are quite a lot that need some fine adjustment/more points added
as they have only been roughly mapped.

Hi
I've seen a few railway ways where it says the source is GPS. I've
tried a couple of times but got absolutely no signal. I guess the
roof of the carriages are shielded.
Short of sticking an aerial on the roof or walking the tracks, what
tips could you give me to get a recording of my journey?
Cheers
Dave F.
