 Double deck buses show an intermediate points display , as well as a final destination . The company 's double decker buses are unique in Scotland in still displaying the destination at both the front and rear . In early mornings and late evenings , some services are curtailed to the city centre or to early termini , in the transition to the night bus service . In such cases , ' Part Route ' is displayed in the intermediate display . Certain routes have all day short working termini , and minor diversions which are often indicated through the use of internal or external ' tram boards ' . Since 2006 double @-@ deck deliveries feature a ' Route Diverted ; intermediate display , used when road closures cause a service to be diverted from its normal route .
