Steam trains puffing and chuffing like this.什么意思?
全文为“Starting from the station with a whistle and a hiss, steam trains puffing and chuffing like this.
请问1、这里的Starting\puffing \chuffing三个词都加ing这不是现在时吧,那这是什么用法呢?如何翻译这三个词?
2、求steam trains puffing and chuffing like this.的翻译?

Starting 做分词,后面是其分词短语.puffing chuffing 现在分词做名词
