Just that really.
Don't know if it's just me but I am not usually the kind of person who gets hot at all very easily and I am boiling.
No air con thingys above me to adjust the temperature and windows don't open, except the ones in between the carriages but I don't really want to spend several hours worth of train journey sitting on the floor in that bit.
Aibu? Or am I just grumpy because the heat is giving me a headache and exacerbating my motion sickness.
