Gedankengang vs Gedanke
thought
'der Gedanke' and 'der Gedankengang' both belong to the area of thinking. 'Ein Gedanke' is more like a single idea, mental image, or intention. 'Ein Gedankengang' is the sequence of several considerations, in other words the path by which someone arrives at an idea or a result. You can confuse the words because both arise in the mind. In practical terms: a thought is a single point; a train of thought is the connection between several points.
Gedankengang
Im Gespräch konnte ich seinen Gedankengang gut verstehen.
In the conversation, I could understand his train of thought well.
Gedanke
Heute Morgen hatte ich den Gedanken, mit dem Fahrrad zur Arbeit zu fahren.
This morning I had the idea of riding my bike to work.
