  We present the results of an outflow and infall survey towards a distance
limited sample of 31 massive star forming regions drawn from the RMS survey.
The presence of young, active outflows is identified from SiO (8-7) emission
and the infall dynamics are explored using HCO$^+$/H$^{13}$CO$^+$ (4-3)
emission. We investigate if the infall and outflow parameters vary with source
properties, exploring whether regions hosting potentially young active outflows
show similarities or differences with regions harbouring more evolved, possibly
momentum driven, "fossil" outflows. SiO emission is detected towards
approximately 46% of the sources. When considering sources with and without an
SiO detection (i.e. potentially active and fossil outflows respectively), only
the $^{12}$CO outflow velocity shows a significant difference between samples,
indicating SiO is more prevalent towards sources with higher outflow
velocities. Furthermore, we find the SiO luminosity increases as a function of
the Herschel 70$\mu$m to WISE 22$\mu$m flux ratio, suggesting the production of
SiO is prevalent in younger, more embedded regions. Similarly, we find
tentative evidence that sources with an SiO detection have a smaller bolometric
luminosity-to-mass ratio, indicating SiO (8-7) emission is associated with
potentially younger regions. We do not find a prevalence towards sources
displaying signatures of infall in our sample. However, the higher energy
HCO$^+$ transitions may not be the best suited tracer of infall at this spatial
resolution in these regions.
