Last year we did trading places from CN to CSA...After about an hour we were ready to go back to CN so we went out front to grab a route cab.
The guard asked if we needed him to call us a cab and we said we would just flag down a route cab.
He asked us to come over to him to discuss this and he told my husband to put on his shirt and then with one whistle, a packed route cab was there for us.
Double decked for my husband and I but not a problem for us.
The guard just smiled and waved us on...
