As a rule we try not to have to walk more than 15-20 minutes with your bags which is why we recommend keeping the weight of your bags between 10-15kg/22-30lb. Suitcases are not recommended for G Adventures trips! Most travellers carry a backpack or rolling bag of small to medium size (no XXL ones please!) as they need to fit under the beds when travelling on sleeper trains. You will also need a day pack/bag to carry water, cameras and other electronics like ipods and mobile phones. If your trip involves overnights in homestays, villages or camping then you usually have the opportunity to rent sleeping bags if need be instead of bringing them with you.
