What are my deductions can I claim uniforms, shoes, tranportation, food , lodging, away from home cell phone , medical bills , union dues , gas miledge , what's the amount per mile , 401k anyone please help

I'm a Conductor for Union Pacific railroad. I'm still learning what I can and can't deduct. My main confusion is the Meal and Incidental deduction. Like an idiot, I didn't save my reciepts for the last year, but I do get a 39 dollar-per-instance Per Diem for my stays in Eau Claire and Adams, WI....

I work for the railroad and would like to know what the deductions are for the railroad worker.

I am a freigt conductor(over the road) for a railroad. What are allowable deductions?

I am employed by a major railroad. Is there a list of items which are tax deductions for this type work. Please help.
