Early freight wagon testing

Here is a selection of freight testing from the early days - most are likely to be braking tests. These fell into two categories:

bulletVacuum brake admission tests to overcome snatches etc with long vacuum-fitted trains
bulletTests on the efficiency of the air brake following the decision in 1964 to abandon the vacuum brake.

Ferry van brake testing

Over an eight day period between 23 April and 30 April 1968,  3T49, a Westinghouse air braked test train operated between Derby RTC and Peak Forest in order to assess the braking capabilities of continental ferry wagons fitted with the P4 Westinghouse air brake. Some of these trains consisted of up to 100 vehicles with a length of 5,000ft.

This poor quality picture shows 3T49, the Westinghouse air braked test train approaching Cromford station on the line between Derby and Manchester in May 1968. The vehicle behind the locomotive in the ex-ER Dynamometer Car DB995000 later to become Test Car 2 and a large number of vans.

Articulated car carriers - Cartic

Cartics On 18th August 1967 former LMS Dynamometer Car No:3 pictured at the head of a test train consisting of a 4 car 'Cartic' articulated car carrier at an unknown location

Liner train1

Derby Type 2 locomotive D6553 with a liner train test train including Dynamometer car No:1 stands outside the Locomotive Works at Derby on 22nd January 1964

D6553 was sent to Derby for static brake tests on January 9th 1964:and then put to work a test train of air-braked freightliner vehicles. One test run was made to Knighton Jc south of Leicester and back on January 10th, full testing commenced on January 16th between Derby & Knighton Jc. Dynamometer car No1 was included in the train. D6553 returned home on January 28th, but was soon recorded as on loan to the Western Region

For details of these tests look here

Where's this? The train is pictured on the exit road from the C&W Works at Derby on 21st January 1964 where it would probably have been assembled and rigged with test equipment as the RTC was still being built. 

Liner train 2

D1806 Chester Brush Type 4 locomotive D1806 with another liner train test train including Dynamometer car No:3 passing Chester box on 15th May 1967. This test train was undertaking 'high speed braking tests' with three types of disc brakes.
