How to parse 乗るもので here ? It doesn't seem to be the もので of "cause/reason".

What does "乗るもので" mean in this sentence?
The "もの" here refers to "経路". So, "前者は電車に乗るもので、後者はバスに乗る必要があります" can be
rephrased as "前者は電車に乗る経路で、後者の経路ではバスに乗る必要があります".

You're right, the もので doesn't mean "cause/reason".

The で is the continuative form (or the te-form) of the copula だ (or です).  
(Grammatically speaking, the continuative form of です is でし and the te-form is
でして.)  
The もの is a noun (物) for "(some)thing", "what" or "the one". もの can function
like a pronoun and here it refers to 移動経路.

So your example can be rephrased as:  
「移動経路はこのように二つあります。前者は電車に乗るもの **だ/です。そして** 、後者はバスに乗る必要があります。」  
↓  
「移動経路はこのように二つあります。前者は電車に乗るもの **で** 、後者はバスに乗る必要があります。」  
(電車に乗る modifies もの as a relative clause.)  
"There are two routes, as you see. / like this. The former is the one with
which you take a train, and as for the latter, you need to take a bus."
