Looking to understand UK Army record abbrevations

[Bill croke]

Hi there, can someone assist please

My father served UK Army 1935 - 1945 in RASC Corps.

His name was Augustus Laurence Doran Croke - service no. S/54873

I'm trying to target his unit to gather information on his unit, its location(s), and how I could obtain further details durning his service period.

His records show he was attached to the following units over his service career. (some writing difficult to understand)
Trng Co
No1 Tng Co.
T (A) Coy
Depot Co
B Depot Co
B Coy Posted C.S.D. Walthanshaw (?)
218 Pct Depot
1652
25 Sup on(?) Sea

PS... I have some photos that may assist

Thanks for any assistance
