We consider Schrödinger operators $$H=-Delta _{g_varepsilon } + V$$H=-Δgε+V on a fibre bundle $$Mmathop {
ightarrow }limits ^{pi }B$$M→πB with compact fibres and a metric $$g_varepsilon $$gε that blows up directions perpendicular to the fibres by a factor $${varepsilon ^{-1}gg 1}$$ε-1≫1. We show that for an eigenvalue $$lambda $$λ of the fibre-wise part of H, satisfying a local gap condition, and every $$Nin mathbb {N}$$N∈N there exists a subspace of $$L^2(M)$$L2(M) that is invariant under H up to errors of order $$varepsilon ^{N+1}$$εN+1. The dynamical and spectral features of H on this subspace can be described by an effective operator on the fibre-wise $$lambda $$λ-eigenspace bundle $$mathcal {E}
ightarrow B$$E→B, giving detailed asymptotics for H.
