What is the voltage at a node between two series voltage sources?

Hopefully the title explains it. As an example, what is the voltage at node one in the schematic below? And more importantly, why? I believe the answer is 0V, but I suppose what I'm thinking is: Why isn't it 125V? Thanks for any help you can give.

Answer

To say the "voltage at" is incorrect. Voltage is a difference.

When people say the voltage at a point, what they really mean is the voltage from said point to ground.

Because there is a ground symbol next to your node with nothing in between you can say that the voltage from the node to ground is zero.
