its an obvious answer: DC SERIES MOTOR

reason:- In trains there are many comartments full of
passengers,so during the starting it requires high starting
torque and in dc series motor torque T proportional to Ia
square and Ia=If,so if the motor started without any load
then the armature current will be very high which may
damage the motor.

Why can't we take NO LOAD TRIAL of motors having V1 mounting??

For a 6.6kV Motor it is recommended to do megger test with 500 V d.c and not more than 5kV d.c but the Hi voltage withstand test should be performed by 12kV AC. Why the dc voltage test should be limited but AC voltage withstand test could be with such a high voltage?
