Problems of travelling in the underground railway of London are :
(i) Huge number of people travelled by,the railways causing overcrowded situation in it.
(ii) The compartments were full of smoke by pipes used by the passengers.
(iii)The atmosphere in the compartments was a mixture of sulphur, coal dust and foul fumes from the gas lamp in the compartment, which made it very unhealthy.
(iv) Many felt that this ‘iron monster’ added to the mess and unhealthiness of the city.
(v) Sometimes, the overcrowded compartments caused almost death to passengers due to asphyxiation and heat.
