Help me please!

Hello everyone. I’m new to Blender and to this forum. I’ve been working with Andrew Prices’ subway tutorial, and having some issues. Due to an origin point issue early on, I’ve made due (mostly) without mirroring, and simply done everything twice. Good extra practice, at least thats how I am justifying my amateur decision.
I’m not sure if you are familiar with the exercise, but everything was going great until LAMPS were introduced into the equation. Can anyone help me. I’m stick.

Thanks
Nick

I’m not sure if I can attach my progress or not to this message.
