Постой, паровоз... // Learn Russian through songs

Постой, паровоз, не стучите, колёса;
Кондуктор, нажми на тормоза!
Я к маменьке родной с последним приветом
Спешу показаться на глаза.
 
Не жди меня, мама, хорошего сына,
Твой сын не такой, как был вчера;
Меня засосала опасная трясина,
И жизнь моя вечная игра.
 
Постой, паровоз, не стучите, колёса;
Есть время взглянуть судьбе в глаза.
Пока ещё не поздно нам сделать остановку,
Кондуктор, нажми на тормоза !

Wait, steam train, don't clatter wheels;
Conductor, put on the brakes!
I hurry to my dear mum with the last greeting
To show my face / to appear in her presence.
 
Don't wait for me, mum, for the good son,
Your son isn't the same he was yesterday;
A dangerous quagmire sucked me in,
And my life is an everlasting game.
 
Wait, steam train, don't clatter wheels;
There's some time to look into eyes of the destiny.
It isn't too late for us yet to make a halt,
Conductor, put on the brakes!

Я к маменьке родной с последним приветом спешу показаться на глаза. It is meant here that he wants to see his mother one more time, he wants to say "hi" to her for the last time, and he hurries because he did something wrong - "твой сын не такой, как был вчера; меня засосала опасная трясина". He doesn't have much time, he knows that he will have to pay for his bad deeds (probably go to prison). "Опасная трясина" probably means here that he got involved with bad guys, have done something wrong and now he has no way out of it.
