Tram and bus travel rules
The following rules apply on the trams and buses.

これ良いな・・・。
Noise nuisance
Please do not disturb your fellow passengers with loud (phone) discussions or music.

Bicycles not permitted
You may bring your bicycle on board the vehicle
これは間違いでしょう。
原文は、、、
Je mag je fiets niet meenemen in het voertuig.なので、否定語が抜けている。

Exception: Tram 26: Bicycle permitted
You may purchase a special ticket and take your bicycle on board, but not in the rush hours, 07:00 – 09:00 and 16:00 – 18:30. Your bicycle must not cause a nuisance to other passengers.

On Sundays and national holidays there is no commute.
これが鉄道とほぼ同じ扱い。

これも日本でもやって欲しい。
No eating or drinking
Eating and drinking is not permitted in the vehicle

日本では躾のできない親が連れた子供くらいで、欧米人には多い。
No feet on the seats
No feet on the seats. This keeps the seats clean and available for your fellow passengers.

Strollers and wheelchairs
Please place your stroller or wheelchair in the designated spot. Fold your stroller up when there is no room available. Wheelchairs take precedence over strollers.

と言うことで、禁止ではないものの、やはり邪魔になってはいけないでしょうね。空いている時に限り、常識の範囲内で。今のご時世、オーバーツーリズが問題となり、”観光客は来るな”と言わないためにも。

We planned to get a tram from our hotel in Amstel to the Central Station with our suitcases on a Saturday when the trams were running every 15 minutes. The first tram was very full and the driver told us we could only get in the back with suitcases but they wouldn't let us on. We lined up ready to get in the back of the next tram but they were also not letting anyone on. We ended up walking to an underground station and taking that instead.
